Note Regarding Forward-Looking Statements

This  Annual  Report  on  Form  10-K  and  the  information  incorporated  herein  by  reference  contain  forward-looking  statements  that  involve  a
number of risks and uncertainties, many of which are beyond our control. Although our forward-looking statements reflect the good faith judgment of our
management, these statements can only be based on facts and factors currently known by us. Consequently, these forward-looking statements are inherently
subject  to  risks  and  uncertainties,  and  actual  results  and  outcomes  may  differ  materially  from  results  and  outcomes  discussed  in  the  forward-looking
statements as a result of various factors, including those set forth below under the caption “Risk Factors.”

Forward-looking  statements  in  this  Annual  Report  and  in  our  other  reports  with  the  Securities  and  Exchange  Commission  (the  “SEC”),  for

example, may include statements regarding:

● our ability to submit of our product candidates through the 505(b)(2) regulatory pathway for approval by the U.S. Food and Drug Administration (the

“FDA”);

● our ability to obtain FDA approval for any of our product candidates;

● our ability to comply with all U.S. and foreign regulations concerning the development, manufacture and sale of our product candidates;

● our ability to maintain, protect and enhance our intellectual property;

● costs associated with initiating and defending intellectual property infringement and other claims;

● our expectations regarding the period during which we qualify as an emerging growth company under the JOBS Act;

● future acquisitions of or investments in complementary companies or technologies; and

● our ability to comply with evolving legal standards and regulations, particularly concerning requirements for being a public company.

In  some  cases,  you  can  identify  forward-looking  statements  by  terms  such  as  “anticipates,”  “believes,”  “continue,”  “could,”  “estimates,”
“expects,” “hopes,” “intends,” “may,” “plan,” “potential,” “predicts,” “projects,” “seeks,” “should,” “will,” “would” or the negative of those terms,
and similar expressions that convey uncertainty of future events or outcomes. In addition, statements that “we believe” and similar statements reflect our
beliefs and opinions on the relevant subject. These statements include, but are not limited to, statements under the captions “Business,” “Risk Factors”
and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as other sections in this report. We discuss many
of  the  risks  associated  with  the  forward-looking  statements  in  this  Annual  Report  on  Form  10-K  in  greater  detail  under  the  heading  “Risk  Factors.”
Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management
to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause
actual results to differ materially from those contained in any forward-looking statements we may make. You should be aware that the occurrence of any of
the  events  discussed  under  the  caption  “Risk  Factors”  and  elsewhere  in  this  report  could  substantially  harm  our  business,  results  of  operations  and
financial condition and that if any of these events occurs, the trading price of our common stock could decline and you could lose all or a part of the value
of your shares of our common stock.

The cautionary statements made in this report are intended to be applicable to all related forward-looking statements wherever they may appear
in this Annual Report on Form 10-K. We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this
Annual Report on Form 10-K. For all forward-looking statements, we claim the protection of the safe harbor for forward-looking statements contained in
the  Private  Securities  Litigation  Reform  Act  of  1995.  Except  as  required  by  law,  we  assume  no  obligation  to  update  our  forward-looking  statements
publicly, or to update the reasons actual results could differ materially from those anticipated in any forward-looking statements, whether as a result of new
information, future events or otherwise.

This  Annual  Report  on  Form  10-K  also  contains  estimates,  projections  and  other  information  concerning  our  industry,  our  business,  and  the
markets for our product candidates, as well as data regarding market research, estimates and forecasts prepared by our management. Information that is
based  on  estimates,  forecasts,  projections,  market  research  or  similar  methodologies  is  inherently  subject  to  uncertainties,  and  actual  events  or
circumstances  may  differ  materially  from  events  and  circumstances  reflected  in  this  information.  Unless  otherwise  expressly  stated,  we  obtained  this
industry,  business,  market  and  other  data  from  reports,  research  surveys,  studies  and  similar  data  prepared  by  market  research  firms  and  other  third
parties, industry, medical and general publications, government data and similar sources. As used in this Annual Report on Form 10-K, unless the context
indicates or otherwise requires, “Eton,” “our company,” “we,” “us,” and “our” refer to Eton Pharmaceuticals, Inc., a Delaware corporation.

You should read the following together with the more detailed information regarding our company, our common stock and our financial statements
and  notes  to  those  statements  appearing  elsewhere  in  this  report  or  incorporated  by  reference.  The  SEC  allows  us  to  “incorporate  by  reference”
information that we file with the SEC, which means that we can disclose important information to you by referring you to those documents. The information
incorporated by reference is considered to be part of this report.

Item 1. Business

Overview

PART I

We  are  a  pharmaceutical  company  focused  on  developing,  acquiring,  and  commercializing  innovative  pharmaceutical  products  that  fulfill  an
unmet  patient  need.  Since  the  formation  of  our  company  in  2017,  we  have  used  our  expertise  in  business  development,  regulatory,  and  product
development to assemble a diversified portfolio of nine products and product candidates. All nine of our product candidates have now been submitted to
the  U.S.  Food  &  Drug  Administration  (“FDA”)  and  three  of  them  have  been  approved  and  commercially  launched.  We  plan  to  continue  growing  our
business through the acquisition of additional late-stage, high-value product candidates.

Product Portfolio

Our product portfolio is comprised of two categories: Orphan Drugs and Royalty Products.

Orphan Drugs

Our orphan drug product category is focused on commercializing products that treat the unmet needs of patients suffering from rare diseases. Our
first orphan product, Alkindi Sprinkle®, was launched in the fourth quarter of 2020. As defined by the FDA, orphan drugs typically address diseases that
impact fewer than 200,000 patients in the United States. Given these small patient populations, products are typically promoted with small, targeted sales
forces  and  distributed  through  high-touch  specialty  pharmacies  that  provide  comprehensive  services  to  patients  or  caregivers.  We  expect  to  continue  to
grow  our  orphan  drug  product  category  and  eventually  commercialize  multiple  products.  We  are  currently  seeking  to  acquire  late-stage  orphan  drug
candidates and expect to add additional product candidates to our pipeline in the near-future.

Alkindi Sprinkle® We currently commercialize Alkindi Sprinkle in the United States. The product was approved by the FDA in September 2020 as a
replacement  therapy  for  Adrenocortical  Insufficiency  (AI)  in  children  under  17  years  of  age.  The  product  is  the  first  and  only  FDA-approved  granule
hydrocortisone  formulation  for  the  treatment  of  AI  designed  for  use  in  children.  We  launched  Alkindi  Sprinkle  in  December  2020  with  a  sales  force
targeting pediatric endocrinologists. We believe there are approximately 10,000 children currently suffering from AI in the United States. Alkindi Sprinkle
is protected by four issued patents that extend to 2034.

In  January  2021,  we  announced  the  acquisition  of  Canadian  rights  to  Alkindi  Sprinkle  and  we  expect  to  pursue  regulatory  approval  of  the  product  in
Canada in the near future.

Dehydrated Alcohol Injection. Our dehydrated alcohol injection product has been submitted to the FDA for the treatment of methanol poisoning. The
application has been granted Orphan Drug Designation and is expected to receive seven years of market exclusivity upon its approval. We submitted the
NDA for the product to the FDA in July 2020, and the application has been assigned a PDUFA date of May 27, 2021.

Royalty Products

Our royalty products category is comprised of products that Eton does not commercialize or products that do not require promotional activities. In
certain cases, the products may be owned and commercialized by a partner that will pay Eton milestones, royalties, and/or profit shares from commercial
sales. In other cases, Eton may retain ownership of the product, but the product may not require promotion or may be commercialized by a co-promotion
partner.

Our royalty products category strategy allows us to monetize our vast experience and talent in business development, regulatory activities, and
product development to generate high returns on our financial investments without being restricted by commercial organization limitations. Specifically,
the royalty model allows us to pursue attractive product opportunities in a wide variety of dosage forms, therapeutic areas, and sales channels without being
restricted to only pursue product opportunities that are complementary to a specific sales infrastructure. By avoiding the financial and human resources
required  to  commercialize  products,  we  believe  we  have  created  a  highly  scalable  business  model  that  can  grow  revenue  significantly  with  minimal
required growth in overhead expenses and headcount.

We believe our asset sales to Azurity Pharmaceuticals (“Azurity”) and Bausch Health Ireland Limited (“Bausch Health” ) have proven the validity
of our business model and have established a successful track record. We expect the diversified portfolio of royalty interests that we have assembled to
provide  significant  high-margin  revenue  to  the  company  for  years  to  come,  and  we  expect  to  continue  growing  our  portfolio.  Future  royalties  may  be
acquired or created via a number of different strategies, including:

● The Initiation of development on Eton’s internal product ideas to be licensed out to commercial partners in the future,
● The licensing of existing development programs where Eton can provide development, regulatory and financial support to advance the programs

and increase the asset’s value before selling or licensing it to a commercial partner, or

● The acquisition of royalty interests in existing commercial products or development candidates.

Biorphen®.  Biorphen  (phenylephrine)  is  the  first  and  only  FDA-approved  formulation  of  ready-to-use  phenylephrine  injection.  Biorphen  in
indicated for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia. The product was
approved in October 2019 and launched in December 2019. We estimate the current addressable market for ready-to-use phenylephrine to be more
than  ten  million  units  of  Biorphen  annually.  Biorphen  primarily  competes  with  FDA-approved  formulations  of  concentrated  phenylephrine
injection, which must be diluted prior to administration to patients, and with unapproved formulations of ready-to-use phenylephrine sold by 503B
compounding  pharmacies.  Eton  owns  the  Biorphen  new  drug  application  (“NDA”),  but  the  product  is  currently  promoted  by  Xellia
Pharmaceuticals’ hospital sales force under a co-promotion agreement. Eton pays Xellia Pharmaceuticals a commission on sales of the product in
certain  channels.  Eton  retains  the  right  to  exit  the  co-promotion  agreement  under  certain  conditions.  We  acquired  U.S.  marketing  rights  to  the
product in February 2019.

Alaway Preservative Free®. Alaway Preservative Free (ketotifen fumarate) is the first and only preservative-free ophthalmic product approved
for  the  treatment  of  allergic  conjunctivitis.  The  preservative-free  formulation  is  designed  to  deliver  an  improved  comfort  profile  to  patients
compared  to  currently  available  ketotifen  ophthalmic  products  that  contain  preservatives.  The  product  is  sold  via  the  over-the-counter  channel.
Currently the market for ketotifen ophthalmic products is estimated to be more than $75 million annually based on data from IRI and IQVIA. We
sold the product rights to Bausch Health in February 2019. Bausch Health is responsible for commercialization of the product which was launched
in February 2021. We are entitled to receive a $1.5 million milestone payment in conjunction with the launch of the product and will receive a
double-digit percentage royalty on the product’s net sales.

Neurology  Oral  Liquids  (Zonisamide,  Topiramate,  and  Lamotrigine).  In  2018  and  2019,  we  assembled  a  portfolio  of  three  neurology  oral
liquid products through in-licensing and internal development. All three products are molecules that are widely used in oral solid forms to treat
epilepsy,  however,  are  not  currently  FDA-approved  in  liquid  formulations.  We  believe  our  formulations  will  be  beneficial  to  patients  suffering
from dysphagia, which is prevalent among pediatric and geriatric patients. In addition, our liquid formulations offer precision dosing, which can
provide patients and caregivers with accurate doses that are lower than or in between the limited strength doses available from oral solid products.

4

 
 
 
 
 
 
 
 
We advanced all three products to NDA submission, and in February 2021 we announced that we sold the three products to Azurity. Under terms
of the agreement, Azurity will pay us milestone payments of up to $45 million and a single digit royalty on net sales of the products. Azurity has taken over
ownership of the products and is responsible for all development, regulatory, and commercial activities.

Zonisamide  Oral  Suspension.  The  product  is  an  innovative  liquid  formulation  of  zonisamide  under  FDA  review  for  the  treatment  of  partial
seizures in patients with epilepsy. The product has been issued a patent, which is now owned by Azurity. The product’s NDA has been assigned a
PDUFA date of May 29, 2021. The current market for zonisamide in oral form is more than $65 million annually according to IQVIA.

Topiramate  Oral  Solution.  The  product  is  an  innovative  liquid  formulation  of  topiramate  under  FDA  review  for  three  indications,  including:
monotherapy for treatment of partial-onset or primary general tonic-clonic seizures in patients two years of age and older; adjunctive therapy for
treatment of partial-onset seizures, including seizures associated with Lennox-Gastaut syndrome in patients two year of age and older; and as a
preventive treatment of migraine in patients 12 years of age and older. Eton’s development partner has submitted a patent on the product. The
product’s NDA has been assigned a PDUFA date of August 6, 2021. The current market for topiramate in oral form is more than $800 million
annually according to IQVIA.

Lamotrigine for Oral Suspension. The product is an innovative liquid formulation of lamotrigine under FDA review for the treatment of partial
on-set seizures, primary generalized tonic-clonic seizures, and seizures of Lennox-Gastaut syndrome in patients two year of age and older. The
product has been issued a patent, which is now owned by Azurity. The product’s NDA application received a Complete Response Letter in March
2020 and the FDA requested changes to the Dosage and Administration section of the product’s Prescribing Information to simplify the dosing
information for intended users. The FDA has requested a human factors validation study with the revised labeling to demonstrate that the intended
users can prepare and administer the oral suspension safely and effectively. Our development partner is in the process of completing the study and
expects the final report to be completed and submitted to the FDA in 2021. The current market for lamotrigine in oral form is more than $700
million annually according to IQVIA.

Cysteine Injection. Cysteine injection is a product candidate for which we have submitted an Abbreviated New Drug Application (“ANDA”) to
the FDA. We believe we are the first-to-file ANDA and should be entitled to 180 days of exclusivity if the patent is successfully challenged. We
expect the NDA to receive tentative approval, in 2021 however, ongoing Paragraph IV litigation is expected to delay final FDA approval beyond
that date. We believe the current market for Cysteine injection is more than $50 million annually.

Ephedrine  Ready-to-Use  Injection.  This  product  is  an  innovative  ready-to-use  formulation  of  a  molecule  that  is  currently  approved  in  a
concentrated  formulation  that  must  be  diluted  prior  to  administration  to  patients.  Hospitals  currently  purchase  non-FDA  approved  ready-to-use
products  from  compounding  facilities,  or  manually  dilute  the  products  in-house.  Our  product  candidate  has  been  developed  in  a  ready-to-use
strength that can be immediately administered to patients, eliminating the need for calculations and additional dilution steps. We believe that, if
approved, our product will offer significant benefits to hospitals over the current compounded products, including longer shelf-life, reduction of
compounding errors, greater sterility assurance, and more consistent supply. Our development partner, Sintetica, has submitted the product’s NDA
and the application has been assigned a PDUFA date of June 18, 2021.

Goals and Strengths

Our goal is to become a leading profitable pharmaceutical company that brings innovative treatments to patients. We believe we are unique in the
pharmaceutical industry in our ability to identify, acquire, and advance products through the development and regulatory process. Our biggest competitive
strengths are:

● Business  development  experience–  our  ability  to  identify  and  execute  transactions  on  under-appreciated  development  assets.  Our  team  has
completed  over  150  business  development  transactions  throughout  their  careers  and  their  industry  connections  and  track  record  provide  the
company with proprietary deal flow. We avoid participating in broker led transactions of auction processes.

● Regulatory expertise  –  Our  knowledge  and  experience  gaining  FDA  approval,  and  particularly  our  knowledge  within  the  505(b)(2)  regulatory
pathway,  which  provides  drug  sponsors  with  the  opportunity  to  leverage  existing  data  or  literature  to  drastically  expedite  drug  development
timelines and reduce investment.

Sales and Marketing

We currently own or have economic interests in three commercial products. We plan to commercialize our orphan products internally with our
own infrastructure. For our royalty category products, we plan to utilize partners for any product commercialization that requires promotional activities. In
our orphan product category, we currently commercialize Alkindi Sprinkle in the United States. We believe we have established the internal infrastructure
necessary to commercialize the product. We have an internal field sales force targeting pediatric endocrinologists and may utilize third-party companies for
additional  promotional  activities.  The  product  is  distributed  to  patients  via  a  specialty  pharmacy,  which  supports  customer  service  and  reimbursement
activities.

In our royalty product category, we rely on partners to commercialize Alaway Preservative Free and Biorphen. We sold Alaway Preservative Free
(previously known as EM-100) to Bausch Health in February 2019, and Bausch Health is responsible for all commercialization activities. Eton receives a
royalty on net sales of the product.

In January 2020 we signed a co-promotion agreement with Xellia Pharmaceuticals for the promotion of Biorphen. Under terms of the agreement,
Xellia’s US-based hospital sales force will promote Biorphen in certain customer channels in exchange for a commission based on net sales realized at
certain customer accounts. Eton owns the Biorphen NDA and the product is sold under Eton’s brand name. The agreement has a five-year term, but allows
Eton to exit under various scenarios, including a change of control, and after 2021 if Biorphen net sales from Xellia designated accounts do not exceed
$29.4 million in 2021, or $42.0 million in 2022 and the following years.

Research and Development

We  currently  have  six  employees  that  support  research  and  development  and  have  a  laboratory  facility  that  supports  product  development  and
testing. In addition, we utilize external sources for various product development activities including the resources of our product development partners for
certain product candidates and also through the use of contract laboratory services on a fee for service model.

Manufacturing and Suppliers

We rely on third-party contract manufacturing organizations (“CMOs”) to manufacture our products. All our manufacturing partners are based in
the  United  States  or  Europe.  We  seek  to  work  with  CMOs  that  have  a  long  history  of  quality  and  FDA  compliance. All  products  are  manufactured  in
compliance with current Good Manufacturing Processes (“cGMP”), and our internal quality system requires us to enter quality agreements with and audit
all of our manufacturers prior to commercializing product. Our choice to rely on external manufacturers significantly reduces the amount of capital invested
in our business and allows us the flexibility to pursue a broad range of opportunities beyond the specific capabilities of a single facility.

Intellectual Property

Our  policy  is  to  seek  to  protect  our  proprietary  position  by,  among  other  methods,  filing  U.S.  and  foreign  patent  applications  related  to  our
proprietary technology, inventions and improvements that are important to the development of our business. We also rely on our trade secrets, know-how
and continuing technological innovation to develop and maintain our proprietary position. We vigorously defend our intellectual property to preserve our
rights and gain the benefit of our technological investments. Our business is not dependent, however, upon any single patent, trademark or contract.

Alkindi Sprinkle is protected by four issued patents that extend to 2034. We intend to seek patent protection on our internally developed products
as  circumstances  warrant  and  we  have  applied  for  trademark  registration  of  the  marks  “Eton”  and  “Eton  Pharmaceuticals”  with  the  U.S.  Patent  and
Trademark Office.

Our  development  partners  for  zonisamide  and  topiramate  have  filed  patent  applications  on  those  products  and  our  development  partner  for
lamotrigine was granted a patent by the United States Patent and Trademark Office for the product’s unique formulation. We expect the lamotrigine patent
to be Orange Book listed after product approval. These patents were assigned to Azurity in February 2021.

Government Regulations and Funding

Pharmaceutical companies are subject to extensive regulation by foreign, federal, state and local agencies, such as the FDA, and various European
regulatory authorities. The manufacture, distribution, marketing and sale of pharmaceutical products are subject to government regulation in the United
States  and  various  foreign  countries.  Additionally,  in  the  United  States,  we  must  follow  rules  and  regulations  established  by  the  FDA  requiring  the
presentation of data indicating that our products are safe and efficacious and are manufactured in accordance with cGMP regulations. If we do not comply
with applicable requirements, we may be fined, the government may refuse to approve our marketing applications or allow us to manufacture or market our
products, and we may be criminally prosecuted. We, our manufacturers and CROs may also be subject to regulations under other foreign, federal, state and
local laws, including, but not limited to, the U.S. Occupational Safety and Health Act, the Resource Conservation and Recovery Act, the Clean Air Act and
import, export and customs regulations as well as the laws and regulations of other countries. The U.S. government has increased its enforcement activity
regarding  illegal  marketing  practices  domestically  and  internationally.  As  a  result,  pharmaceutical  companies  must  ensure  their  compliance  with  the
Foreign Corrupt Practices Act and federal healthcare fraud and abuse laws, including the False Claims Act.

These regulatory requirements impact our operations and differ from one country to another, so that securing the applicable regulatory approvals
of one country does not imply the approval of another country. The approval procedures involve high costs and are manpower intensive, usually extend
over many years and require highly skilled and professional resources.

FDA Market Approval Process

The steps usually required to be taken before a new drug may be marketed in the United States generally include:

● completion of pre-clinical laboratory and animal testing;

● completion of required chemistry, manufacturing and controls testing;

● the submission to the FDA of an investigational new drug, or IND, the application for which must be evaluated and found acceptable by the

FDA before human clinical trials may commence;

● performance of adequate and well-controlled human clinical trials to establish the safety, pharmacokinetics and efficacy of the proposed drug

for its intended use;

● submission and approval of an NDA; and

● agreement with FDA of the language on the package insert.

Clinical  studies  are  conducted  under  protocols  detailing,  among  other  things,  the  objectives  of  the  study,  what  types  of  patients  may  enter  the
study, schedules of tests and procedures, drugs, dosages, and length of study, as well as the parameters to be used in monitoring safety, and the efficacy
criteria  to  be  evaluated.  A  protocol  for  each  clinical  study  and  any  subsequent  protocol  amendments  must  be  submitted  to  the  FDA  as  part  of  the  IND
process.

Clinical trials are usually conducted in three phases. Phase 1 clinical trials are normally conducted in small groups of healthy volunteers to assess
safety of various dosing regimens and pharmacokinetics. After a safe dose has been established, in Phase 2 clinical trials the drug is administered to small
populations of sick patients to look for initial signs of efficacy in treating the targeted disease or condition and to continue to assess safety. Phase 3 clinical
trials are usually multi-center, double-blind controlled trials in larger numbers of subjects at various sites to assess as fully as possible both the safety and
effectiveness of the drug.

Clinical trials must be conducted in accordance with the FDA’s good clinical practices (“GCP”) requirements. The FDA may order the temporary
or  permanent  discontinuation  of  a  clinical  study  at  any  time  or  impose  other  sanctions  if  it  believes  that  the  clinical  study  is  not  being  conducted  in
accordance  with  FDA  requirements  or  that  the  participants  are  being  exposed  to  an  unacceptable  health  risk.  An  institutional  review  board  (“IRB”)
generally  must  approve  the  clinical  trial  design  and  patient  informed  consent  at  study  sites  that  the  IRB  oversees  and  also  may  halt  a  study,  either
temporarily  or  permanently,  for  failure  to  comply  with  the  IRB’s  requirements,  or  may  impose  other  conditions.  Additionally,  some  clinical  studies  are
overseen by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board or committee. This
group recommends whether or not a trial may move forward at designated check points based on access to certain data from the study. The clinical study
sponsor may also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate.

As a product candidate moves through the clinical testing phases, manufacturing processes are further defined, refined, controlled and validated.
The level of control and validation required by the FDA increases as clinical studies progress. We and the third-party manufacturers on which we rely for
the manufacture of our product candidates and their respective components (including the API) are subject to requirements that drugs be manufactured,
packaged and labeled in conformity with cGMP. To comply with cGMP requirements, manufacturers must continue to spend time, money and effort to
meet  requirements  relating  to  personnel,  facilities,  equipment,  production  and  process,  labeling  and  packaging,  quality  control,  recordkeeping  and  other
requirements.

Assuming  completion  of  all  required  testing  in  accordance  with  all  applicable  regulatory  requirements,  detailed  information  on  the  product
candidate is submitted to the FDA in the form of an NDA, requesting approval to market the product for one or more indications, together with payment of
a user fee, unless waived. An NDA includes all relevant data available from pertinent nonclinical and clinical studies, including negative or ambiguous
results as well as positive findings, together with detailed information on the chemistry, manufacture, controls and proposed labeling, among other things.
To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the product candidate for
its intended use to the satisfaction of the FDA.

If  an  NDA  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review  of  the  NDA.  Under  the  Prescription  Drug  User  Fee  Act
(“PDUFA”) the FDA’s goal is to complete its initial review and respond to the applicant within ten months of submission, unless the application relates to
an unmet medical need, or is for a serious or life-threatening indication, in which case the goal may be within six months of NDA submission. However,
the review process and the target response date under PDUFA may be extended if the FDA requests or the NDA sponsor otherwise provides additional
information or clarification regarding information already provided in the NDA. During its review of an NDA, the FDA may refer the application to an
advisory  committee  for  review,  evaluation  and  recommendation  as  to  whether  the  application  should  be  approved.  The  FDA  is  not  bound  by  the
recommendation of an advisory committee, but it typically follows such recommendations. Data from clinical studies are not always conclusive and the
FDA and/or any advisory committee it appoints may interpret data differently than the applicant.

After  the  FDA  evaluates  the  NDA  and  inspects  manufacturing  facilities  where  the  drug  product  and/or  its  API  will  be  produced,  it  will  either
approve commercial marketing of the drug product with prescribing information for specific indications or issue a complete response letter indicating that
the application is not ready for approval and stating the conditions that must be met in order to secure approval of the NDA. If the complete response letter
requires additional data and the applicant subsequently submits that data, the FDA nevertheless may ultimately decide that the NDA does not satisfy its
criteria for approval. The FDA could also approve the NDA with a Risk Evaluation and Mitigation Strategies (“REMS”) plan to mitigate risks, which could
include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and
other  risk  minimization  tools.  The  FDA  also  may  condition  approval  on,  among  other  things,  changes  to  proposed  labeling,  development  of  adequate
controls  and  specifications,  or  a  commitment  to  conduct  post-marketing  testing.  Such  post-marketing  testing  may  include  Phase  4  clinical  trials  and
surveillance to further assess and monitor the product’s safety and efficacy after approval.

If the FDA approves one of our product candidates, we will be required to comply with a number of post-approval regulatory requirements. We
would  be  required  to  report,  among  other  things,  certain  adverse  reactions  and  production  problems  to  the  FDA,  provide  updated  safety  and  efficacy
information  and  comply  with  requirements  concerning  advertising  and  promotional  labeling  for  any  of  our  products.  Also,  quality  control  and
manufacturing  procedures  must  continue  to  conform  to  cGMP  after  approval,  and  the  FDA  periodically  inspects  manufacturing  facilities  to  assess
compliance  with  cGMP,  which  imposes  extensive  procedural,  substantive  and  record  keeping  requirements.  If  we  seek  to  make  certain  changes  to  an
approved product, such as certain manufacturing changes, we will need FDA review and approval before the change can be implemented. For example, if
we change the manufacturer of a product or our API, the FDA may require stability or other data from the new manufacturer, and such data will take time
and are costly to generate, and the delay associated with generating these data may cause interruptions in our ability to meet commercial demand, if any.
While physicians may use products for indications that have not been approved by the FDA, we may not label or promote the product for an indication that
has not been approved. Securing FDA approval for new indications is similar to the process for approval of the original indication and requires, among
other things, submitting data from adequate and well-controlled studies that demonstrate the product’s safety and efficacy in the new indication. Even if
such studies are conducted, the FDA may not approve any change in a timely fashion, or at all.

The FDA may also require post-marketing testing, or Phase 4 testing, as well as risk minimization action plans and surveillance to monitor the

effects of an approved product or place conditions or an approval that could otherwise restrict the distribution or use of the product.

Section 505(b)(2) New Drug Applications

We intend to submit applications for certain product candidates via the 505(b)(2) regulatory pathway. As an alternate path for FDA approval of
new  indications  or  new  formulations  of  previously  approved  products,  a  company  may  submit  a  Section  505(b)(2)  NDA,  instead  of  a  “stand-alone”  or
“full” NDA. Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act (“FDCA”) was enacted as part of the Drug Price Competition and Patent Term
Restoration Act of 1984, otherwise known as the Hatch-Waxman Amendments. Section 505(b)(2) permits the submission of an NDA where at least some
of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of
reference. Some examples of products that may be allowed to follow a 505(b)(2) path to approval are drugs that have a new dosage form, strength, route of
administration, formulation or indication.

The Hatch-Waxman Amendments permit the applicant to rely upon certain published nonclinical or clinical studies conducted for an approved
product or the FDA’s conclusions from prior review of such studies. The FDA may require companies to perform additional studies or measurements to
support  any  changes  from  the  approved  product.  The  FDA  may  then  approve  the  new  product  for  all  or  some  of  the  labeled  indications  for  which  the
reference product has been approved, as well as for any new indication supported by the Section 505(b)(2) application. While references to nonclinical and
clinical data not generated by the applicant or for which the applicant does not have a right of reference are allowed, all development, process, stability,
qualification and validation data related to the manufacturing and quality of the new product must be included in an NDA submitted under Section 505(b)
(2).

To  the  extent  that  the  Section  505(b)(2)  applicant  is  relying  on  the  FDA’s  conclusions  regarding  studies  conducted  for  an  already  approved
product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Approved Drug Products with
Therapeutic Equivalence Evaluations, or Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed;
(ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or
(iv) the listed patent is invalid or will not be infringed by the new product. The Section 505(b)(2) application also will not be approved until any non-patent
exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the reference product has expired. If the
Orange Book certifications outlined above are not accomplished, the Section 505(b)(2) applicant may invest a significant amount of time and expense in
the development of its products only to be subject to significant delay and patent litigation before its products may be commercialized.

Section 505(j) Abbreviated New Drug Applications

The 505(j) pathway is used for product candidates that are therapeutically equivalent to an approved product. The underlying premise of the 505(j)
pathway is that a product candidate classified as therapeutically equivalent can be substituted for the approved product with the full expectation that the
substituted  product  will  produce  the  same  clinical  effect  and  safety  profile  as  the  approved  product  when  administered  under  the  same  conditions.  A
product  candidate  utilizing  the  505(j)  pathway  requires  an  abbreviated  new  drug  application,  or  ANDA,  which  relies  on  the  FDA’s  finding  that  the
previously approved drug candidate is safe and effective. An ANDA generally must contain information to show that the product candidate is the same as
the  approved  product  with  respect  to  API,  conditions  of  use,  route  of  administration,  dosage  form,  strength  and  labeling,  with  certain  permissible
differences, and is the bioequivalent of the approved drug. The 505(j) pathway typically requires no clinical testing other than a bioequivalence trial. While
the  505(j)  pathway  is  typically  shorter  and  less  expensive  than  the  505(b)(2)  pathway,  the  505(b)(2)  pathway  allows  greater  flexibility  as  to  the
characteristics of the product candidate.

Other U.S. Healthcare Laws and Compliance Requirements

For  products  distributed  in  the  United  States,  we  will  also  be  subject  to  additional  healthcare  regulation  and  enforcement  by  the  federal

government and the states in which we conduct our business. Applicable federal and state healthcare laws and regulations include the following:

● The  U.S.  Anti-Kickback  Statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  offering,  receiving,  or
providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase,
order,  lease,  or  recommendation  of,  any  good  or  service,  for  which  payment  may  be  made  under  federal  healthcare  programs  such  as
Medicare and Medicaid;

● The  federal  civil  and  criminal  false  claims  laws,  including  the  U.S.  False  Claims  Act,  can  be  enforced  by  individuals,  on  behalf  of  the
government,  through  civil  whistleblower  or  qui  tam  actions,  and  the  civil  monetary  penalties  law,  prohibits  individuals  or  entities  from,
among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government  claims  for  payment  that  are  false  or
fraudulent or making a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government;

● The Health  Insurance  Portability  and  Accountability  Act  of  1996  (“HIPAA”),  which  prohibits,  among  other  things,  executing  a  scheme  to
defraud  any  healthcare  benefit  program  and  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a  material  fact  or  making  any
materially false statement in connection with the delivery of or payment for healthcare benefits, items, or services;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  and  their  implementing  regulations,
imposes  obligations,  including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of
individually identifiable health information;

● The Physician  Payments  Sunshine  Act  which  requires  certain  manufacturers  of  drugs,  devices,  biologics  and  medical  supplies  for  which
payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the
Centers  for  Medicare  &  Medicaid  Services  (“CMS”)  information  related  to  payments  or  other  transfers  of  value  made  to  physicians  and
teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and

● Analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangements and
claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers, state laws that
require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance
guidance  promulgated  by  the  federal  government;  state  and  local  laws  that  require  drug  manufacturers  to  report  information  related  to
payments  and  other  transfers  of  value  to  physicians  and  other  healthcare  providers  or  marketing  expenditures;  state  laws  that  require  the
reporting  of  information  related  to  drug  pricing;  state  and  local  laws  requiring  the  registration  of  pharmaceutical  sales  and  medical
representatives;  and  state  and  foreign  laws,  such  as  the  General  Data  Protection  Regulation  (EU)  2016/679,  governing  the  privacy  and
security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted
by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory safe harbors, it is possible that some of
our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the federal or
state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including significant criminal, civil, and
administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, integrity oversight
and reporting obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations.

Reimbursement

Sales of our products in the United States may depend, in part, on the extent to which the costs of the products will be covered and reimbursed by
third-party  payors,  such  as  government  health  programs,  commercial  insurance  and  managed  health  care  organizations.  These  third-party  payors  are
increasingly challenging the prices charged for medical products and services. Additionally, the containment of health care costs has become a priority of
federal  and  state  governments,  and  the  prices  of  drugs  have  been  a  focus  in  this  effort.  The  United  States  government,  state  legislatures  and  foreign
governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  restrictions  on  reimbursement  and
requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could further limit our net revenue and results. If these third-party payors do not consider our products to
be cost-effective compared to other available therapies, they may not cover our products after approval as a benefit under their plans or, if they do, the level
of payment may not be sufficient to allow us to sell our products on a profitable basis.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, (the “MMA”), imposed new requirements for the distribution and
pricing of prescription drugs for Medicare beneficiaries and included a major expansion of the prescription drug benefit under Medicare Part D. Under Part
D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs.
Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike
Medicare Parts A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs,
and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug
formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or
class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government
payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated
prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the
MMA applies only to drug benefits for Medicare beneficiaries, private third-party payors often follow Medicare coverage policy and payment limitations in
setting  their  own  payment  rates.  Any  reduction  in  payment  that  results  from  the  MMA  may  result  in  a  similar  reduction  in  payments  from  non-
governmental payors.

Decreases in third-party reimbursement for our products or a decision by a third-party payor to not cover our products could reduce physician

usage of the products and have a material adverse effect on our sales, results of operations and financial condition.

Healthcare Reform

In  the  United  States  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes
regarding the health care system that could prevent or delay marketing approval pharmaceutical products, restrict or regulate post-approval activities and
affect our ability to profitably sell our product candidates. Legislative and regulatory proposals have been made to expand post-approval requirements and
restrict sales and promotional activities for pharmaceutical products.

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act,
(collectively, the “Health Care Reform Law”) was enacted, which substantially changes the way health care is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. The Health Care Reform Law, among other things, imposed reporting requirements on
manufacturers related to drug samples and financial relationships with physicians and teaching hospitals, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations,
established annual fees on manufacturers of certain branded prescription drugs, and established a Medicare Part D coverage gap discount program.

11

 
 
 
 
 
 
 
 
 
Some of the provisions of the Health Care Reform Law have yet to be implemented, and there have been judicial and Congressional challenges to
certain aspects of the Health Care Reform Law, as well as recent efforts by the former Trump administration to repeal or replace certain aspects of the
Health Care Reform Law. Since January 2017, former President Trump had signed two executive orders and other directives designed to delay, circumvent
or loosen certain requirements mandated by the Health Care Reform Law. Concurrently, Congress has considered legislation that would repeal or repeal
and  replace  all  or  part  of  the  Health  Care  Reform  Law.  While  Congress  has  not  passed  comprehensive  repeal  legislation,  two  bills  affecting  the
implementation of certain taxes under the Health Care Reform Law have been signed into law. The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) included
a provision which repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the Health Care Reform Law on certain
individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” On January
22, 2018, former President Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Health
Care Reform Law-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed
on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act
of  2018,  among  other  things,  amended  the  Health  Care  Reform,  effective  January  1,  2019,  to  increase  from  50  percent  to  70  percent  the  point-of-sale
discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans,
commonly referred to as the “donut hole”. On December 14, 2018, a Texas U.S. District Court Judge ruled that the Health Care Reform is unconstitutional
in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Act. While the Texas U.S. District Court Judge, as well as the
Trump administration and CMS, have stated that the ruling will have no immediate effect pending appeal of the decision, it is unclear how this decision,
subsequent appeals, and other efforts to repeal and replace the Health Care Reform will impact the Health Care Reform Law.

In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. These
changes  include,  among  others,  aggregate  reductions  of  Medicare  payments  to  providers  of  up  to  2%  per  fiscal  year  and  an  increase  in  the  statute  of
limitations period for the government to recover overpayments to providers from three to five years.

Further,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of  pharmaceutical  pricing  practices  in  light  of  the  rising  cost  of
prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for products. For example, the Trump administration released a “Blueprint” to lower drug
prices and reduce out of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power
of  certain  federal  healthcare  programs,  incentivize  manufacturers  to  lower  the  list  price  of  their  products,  and  reduce  the  out-of-pocket  costs  of  drug
products paid by consumers. On January 31, 2019, the Health and Human Services (“HHS”) Office of Inspector General proposed modifications to the
U.S. Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among other things, if finalized,
will affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit managers working with
these organizations. While some of these and other proposed measures may require additional authorization to become effective, Congress and government
administration officials have each indicated that they will continue to seek new legislative and/or administrative measures to control drug costs.

Moreover, in December 2016, the 21st Century Cures Act was signed into law. The 21st Century Cures Act, among other things, is intended to
modernize the regulation of drugs and biologics and spur innovation, but it has not yet been fully implemented and its ultimate implementation is unclear.
Additionally,  the  Trump  administration  has  taken  several  executive  actions,  including  the  issuance  of  a  number  of  executive  orders,  that  could  impose
significant  burdens  on,  or  otherwise  materially  delay,  the  FDA’s  ability  to  engage  in  routine  regulatory  and  oversight  activities  such  as  implementing
statutes through rulemaking, issuance of guidance and review and approval of marketing applications.

Risks

You  should  carefully  consider  the  risks  set  forth  in  the  section  of  this  prospectus  entitled  “Risk  Factors”  beginning  on  page  16  of  this  Annual

Report, including, but not limited to, the following:

● We are a specialty pharmaceutical company with a limited operating history, and it is difficult for potential investors to evaluate our business.

● Our business is adversely affected by the ongoing coronavirus pandemic and the impact could be material.

● We may have significant research, regulatory and development expenses as we advance our product candidates.

● We may need to grow the size of our organization, and we may experience difficulties in managing this growth.

● If product  liability  lawsuits  are  brought  against  us,  we  may  incur  substantial  liabilities  and  may  be  required  to  limit  commercialization  of  our

product candidates.

● We may acquire businesses or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

● We  rely  significantly  on  information  technology  and  any  failure,  inadequacy,  interruption  or  security  lapse  of  that  technology,  including  any

cybersecurity incidents, could harm our ability to operate our business effectively.

● Sales of counterfeits of any of our product candidates, as well as unauthorized sales of any of our product candidates, may have adverse effects on

our revenues, business and results of operations and damage our brand and reputation.

● We  have  entered  into  several  arrangements  with  related  parties  for  the  development  and  marketing  of  certain  product  candidates  and  these

arrangements present potential conflicts of interest.

● We depend entirely on the success of Biorphen and our product candidates. If we are unable to generate revenues from our product candidates, our

ability to create stockholder value will be limited.

● We  face  competition  from  other  biotechnology  and  pharmaceutical  companies  and  our  operating  results  will  suffer  if  we  fail  to  compete

effectively.

● Our competitors may obtain FDA or other regulatory approval for comparable products more rapidly than we may obtain approval for ours, and
the risk of our competitors doing so may lead us to develop drug candidates without disclosing certain information with regard to such candidates.

● If we  are  not  able  to  obtain  any  required  regulatory  approvals  for  our  product  candidates,  we  will  not  be  able  to  commercialize  our  product

candidate and our ability to generate revenue will be limited.

● If  the  FDA  does  not  conclude  that  our  product  candidates  satisfy  the  requirements  for  the  505(b)(2)  regulatory  approval  pathway,  or  if  the
requirements for approval of any of our product candidates under Section 505(b)(2) are not as we expect, the approval pathway for our product
candidates  will  likely  take  significantly  longer,  cost  significantly  more  and  encounter  significantly  greater  complications  and  risks  than
anticipated, and in any case may not be successful.

● An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or

prevent the review or approval of our product candidate.

● Even if we receive regulatory approval for any of our product candidates, we may not be able to successfully commercialize the product, and the

revenue that we generate from its sales, if any, may be limited.

● We are  subject  to  ongoing  obligations  and  continued  regulatory  review,  which  may  result  in  significant  additional  expense.  Additionally,  our
product candidates could be subject to labeling and other restrictions and withdrawal from the market and we may be subject to penalties if we fail
to comply with regulatory requirements or if we experience unanticipated problems with our product candidates.

● Significant additional labeling or warning requirements or limitations on the availability of our products may inhibit sales of affected products.

● Current  and  future  legislation  may  increase  the  difficulty  and  cost  for  us  to  obtain  marketing  approval  of  and  commercialize  our  product

candidates and affect the prices we may obtain.

● Our future  growth  may  depend,  in  part,  on  our  ability  to  penetrate  international  markets,  where  we  would  be  subject  to  additional  regulatory

burdens and other risks and uncertainties.

● If we market Biorphen or any of our product candidates in a manner that violates health care fraud and abuse laws, or if we violate government

price reporting laws, we may be subject to civil or criminal penalties.

● We may not be able to establish agreements with third parties with whom we wish to collaborate and, if we are able to establish them, we may not
be able to establish them on commercially reasonable terms, which could result in alterations or delays of our development and commercialization
plans.

● We expect  to  rely  on  third  parties  to  conduct  clinical  trials  for  our  product  candidates.  If  these  third  parties  do  not  successfully  carry  out  their
contractual  duties  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain  regulatory  approval  for  or  commercialize  any  of  our  product
candidates and our business would be substantially harmed.

● We enter  into  various  contracts  in  the  normal  course  of  our  business,  some  or  all  of  which  may  require  us  to  indemnify  the  other  party  to  the
contract.  In  the  event  we  have  to  perform  under  these  indemnification  provisions,  it  could  have  an  adverse  effect  on  our  business,  financial
condition and results of operations.

● Our  Chief  Executive  Officer  holds  ownership  interest  in  some  of  the  third  parties  we  have  entered  into  agreements  with.  The  terms  and  fee
arrangements of these agreements, we believe, approximate the terms and fee arrangements of an agreement that would have been obtained in an
arm’s length and unaffiliated transaction. Nonetheless, this may expose us to claims of interested transactions and other fiduciary suits.

● Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product candidates for

any indications could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

● Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be

predictive of future trial results.

● Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.

● We are subject to extensive laws and regulations related to data privacy, and our failure to comply with these laws and regulations could harm our

business.

● We  will  depend  on  rights  to  certain  pharmaceutical  compounds  that  have  been  acquired  by  us.  We  do  not  have  complete  control  over  these

pharmaceutical compounds and any loss of our rights to them could prevent us from selling our products.

● It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.

● We may not be able to protect our intellectual property rights throughout the world.

● Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our

ability to protect our products.

● Our  product  candidates  may  infringe  the  intellectual  property  rights  of  others,  which  could  increase  our  costs  and  delay  or  prevent  our

development and commercialization efforts.

● Others  may  claim  an  ownership  interest  in  our  intellectual  property,  which  could  expose  us  to  litigation  and  have  an  adverse  effect  on  our

prospects.

● We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used or

disclosed alleged confidential information or trade secrets of their former employers.

Item 1A. Risk Factors

We operate in a dynamic and rapidly changing environment that involves numerous risks and uncertainties. Certain factors may have a material
adverse  effect  on  our  business,  financial  condition  and  results  of  operations,  and  you  should  carefully  consider  them.  Accordingly,  in  evaluating  our
business, we encourage you to consider the following discussion of risk factors, in its entirety, in addition to other information contained in this Annual
Report on Form 10-K and our other public filings with the SEC. Other events that we do not currently anticipate or that we currently deem immaterial may
also affect our results of operations and financial condition.

Risks Relating to Our Business

We are a specialty pharmaceutical company with a limited operating history, and it is difficult for potential investors to evaluate our business.

We  are  a  specialty  pharmaceutical  company  founded  in  April  2017  and  have  only  recently  commenced  revenue-producing  operations  and  our
historical  operations  have  primarily  consisted  of  the  preliminary  formulation,  testing  and  development  of  our  various  product  candidates.  Our  limited
operating  history  makes  it  difficult  for  potential  investors  to  evaluate  our  initial  product  candidates  or  our  prospective  operations.  As  an  early-stage
company, we are subject to all the risks inherent in the initial organization, financing, expenditures, complications and delays in a new business. Further,
biopharmaceutical  product  development  is  a  highly  speculative  undertaking,  involves  a  substantial  degree  of  risk  and  is  a  capital-intensive  business.
Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by companies in the early
stages of product development and commercialization, especially clinical-stage biopharmaceutical companies such as ours. As a company with a limited
operating history, we may be unable to:

● successfully implement or execute our current business plan, or develop a business plan that is sound;

● successfully complete clinical trials and obtain regulatory approval for the marketing of our additional product candidates;

● successfully contract for the manufacture of our clinical drug products and establish a commercial drug supply;

● secure market exclusivity or adequate intellectual property protection for our product candidates;

● attract and retain an experienced management and advisory team; or

● raise sufficient funds in the capital markets to effectuate our business plan, including clinical development, regulatory approval and ongoing

commercialization for our product candidates.

There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability. If we cannot successfully

execute any one of the foregoing, our business may not succeed.

Our business is adversely affected by the ongoing coronavirus pandemic and the impact could be material.

Public  health  outbreaks,  epidemics  or  pandemics  have  had,  and  could  in  the  future  have,  an  adverse  impact  on  our  operations  and  financial
condition.  The  continuing  pandemic  caused  by  the  novel  strain  of  coronavirus  (COVID-19)  has  caused  many  countries,  including  the  United  States,  to
declare national emergencies and implement preventive measures such as travel bans and shelter-in-place or total lock-down orders, some of which have
eased. The continuation or re-implementation of these bans and orders remains uncertain. In some cases, these bans and orders have influenced certain
aspects  of  our  business.  For  example,  we  began  commercializing  our  Biorphen  product  in  December  2019;  however,  we  have  encountered  difficulty  in
creating significant market pull-through demand for Biorphen in 2020 as our in-person sales calls to key personnel at hospitals and surgical centers and
introductory product presentation seminars were cancelled as a result of the COVID-19 pandemic. We are working on other promotional efforts to drive
further adoption in the market, but we expect that our Biorphen sales and marketing efforts will continue to be adversely affected by the pandemic in 2021.
COVID-19 may also affect our ability to complete recruitment and data analysis for our clinical trials and our ability to conduct research and development
of our complement programs in our planned timeframe. The extent to which COVID-19 impacts our operations will depend on future developments, which
are highly uncertain and cannot be predicted with confidence, including the duration and severity of the outbreak, and the actions that may be required to
contain COVID-19 or treat its impact. In particular, as a result of the COVID-19 pandemic, we may experience disruptions that could severely impact our
business, preclinical studies, drug manufacturing and clinical trials including:

● delays or difficulties in enrolling patients in our human factor study for Lamotrigine Oral Suspension (ET-105);

● diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and

hospital staff supporting the conduct of our clinical trials;

● interruption of  key  clinical  trial  activities,  such  as  clinical  trial  site  data  monitoring,  due  to  limitations  on  travel  imposed  or  recommended  by
federal  or  state  governments,  employers  and  others  or  interruption  of  clinical  trial  subject  visits  and  study  procedures,  which  may  impact  the
integrity of subject data and clinical study endpoints;

● interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and approval timelines; and

● interruption of, or delays in promoting our products in-person, at conferences and at hospitals due to limitations on travel and in-person gatherings

imposed or recommended by federal or state governments.

We may need to grow the size of our organization, and we could experience difficulties in managing this growth.

As  our  development  and  commercialization  plans  and  strategies  develop,  we  may  need  to  expand  the  size  of  our  employee  and
consultant/contractor  base.  Future  growth  would  impose  significant  added  responsibilities  on  members  of  management,  including  the  need  to  identify,
recruit, maintain, motivate and integrate additional employees. In addition, our management may have to divert a disproportionate amount of its attention
away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. Our future financial performance and our
ability to commercialize our product candidates and any other future product candidates and our ability to compete effectively will depend, in part, on our
ability to effectively manage our future growth.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product
candidates.

We face a potential risk of product liability as a result of the commercialization of our approved products and clinical testing of our new product
candidates and will face an even greater risk if we commercialize our current product candidates or any other future product. For example, we may be sued
if our approved products or any product we develop, including any of our product candidates, or any materials that we use in our products allegedly causes
injury  or  is  found  to  be  otherwise  unsuitable  during  product  testing,  manufacturing,  marketing  or  sale.  Any  such  product  liability  claims  may  include
allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach of
warranties. In the United States, claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against
product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates. Even successful defense
would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

● decreased demand for our current products or any of our product candidates or any future products that we may develop;

● injury to our reputation;

● withdrawal of clinical trial participants;

● costs to defend the related litigation;

● a diversion of management’s time and our resources;

● substantial monetary awards to trial participants or patients;

● product recalls, withdrawals or labeling, marketing or promotional restrictions;

● the inability to commercialize some or all of our product candidates; and

● a decline in the value of our stock.

We  carry  product  liability  insurance  we  consider  adequate  for  our  current  level  of  expected  product  sales,  clinical  testing  and  product
development.  Our  inability  to  obtain  and  retain  sufficient  product  liability  insurance  at  an  acceptable  cost  to  protect  against  potential  product  liability
claims could prevent or inhibit the commercialization of our approved products or additional products we develop. Although we will endeavor to obtain
and  maintain  such  insurance  in  coverage  amounts  we  deem  adequate,  any  claim  that  may  be  brought  against  us  could  result  in  a  court  judgment  or
settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance
policies also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts
awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be
able to obtain, sufficient capital to pay such amounts.

We may acquire businesses or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

We  may  acquire  additional  businesses  or  products,  form  strategic  alliances  or  create  joint  ventures  with  third  parties  that  we  believe  will
complement or augment our existing business. If we acquire businesses with promising markets or technologies, we may not be able to realize the benefit
of  acquiring  such  businesses  if  we  are  unable  to  successfully  integrate  them  with  our  existing  operations  and  company  culture.  We  may  encounter
numerous difficulties in developing, manufacturing and marketing any new products resulting from a strategic alliance or acquisition that delay or prevent
us  from  realizing  their  expected  benefits  or  enhancing  our  business.  We  cannot  assure  you  that,  following  any  such  acquisition,  we  will  achieve  the
expected synergies to justify the transaction.

We  rely  significantly  on  information  technology  and  any  failure,  inadequacy,  interruption  or  security  lapse  of  that  technology,  including  any
cybersecurity incidents, could harm our ability to operate our business effectively.

Despite the implementation of security measures, our internal computer systems and those of third parties with which we contract are vulnerable
to  damage  from  cyber-attacks,  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and  telecommunication  and  electrical  failures.
System  failures,  accidents  or  security  breaches  could  cause  interruptions  in  our  operations,  and  could  result  in  a  material  disruption  of  our  product
development and clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. Cybersecurity
attacks in particular are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic
security breaches that could lead to disruptions in systems, misappropriation of our confidential or otherwise protected information and corruption of data.
The loss, theft or sabotage of product development or clinical trial data could result in delays in our regulatory approval efforts and significantly increase
our  costs  to  recover  or  reproduce  the  data.  To  the  extent  that  any  disruption  or  security  breach  were  to  result  in  a  loss  of,  or  damage  to,  our  data  or
applications,  or  inappropriate  disclosure  of  confidential  or  proprietary  information,  we  could  incur  liability  and  our  development  programs  and  the
development of our product candidates could be delayed.

Sales of counterfeits of any of our product candidates, as well as unauthorized sales of any of our product candidates, may have adverse effects on our
revenues, business and results of operations and damage our brand and reputation.

Our  current  approved  products  or  our  new  product  candidates  may  become  subject  to  competition  from  counterfeit  pharmaceutical  products,
which are pharmaceutical products sold under the same or very similar brand names and/or having a similar appearance to genuine products, but which are
sold without proper licenses or approvals. Such products divert sales from genuine products, often are of lower cost, often are of lower quality (having
different ingredients or formulations, for example), and have the potential to damage the reputation for quality and effectiveness of the genuine product.
Obtaining regulatory approval for our product candidates is a complex and lengthy process. If during the period while the regulatory approval is pending,
illegal sales of counterfeit products begin, consumers may buy such counterfeit products, which could have an adverse impact on our revenues, business
and results of operations. In addition, if illegal sales of counterfeits result in adverse side effects to consumers, we may be associated with any negative
publicity resulting from such incidents. Although pharmaceutical regulation, control and enforcement systems throughout the world have been increasingly
active  in  policing  counterfeit  pharmaceuticals,  we  may  not  be  able  to  prevent  third  parties  from  manufacturing,  selling  or  purporting  to  sell  counterfeit
products competing with our current products or our new product candidates. Such sales may also be occurring without our knowledge. The existence and
any  increase  in  production  or  sales  of  counterfeit  products  or  unauthorized  sales  could  negatively  impact  our  revenues,  brand  reputation,  business  and
results of operations.

19

 
 
 
 
 
 
 
 
Risks Related to Product Development, Regulatory Approval, Manufacturing and Commercialization

We  depend  entirely  on  the  success  of  current  approved  products  and  our  new  product  candidates.  If  we  are  unable  to  generate  revenues  from  our
approved products and new product candidates, our ability to create stockholder value will be limited.

We have various product candidates under review with the FDA and are in the early stages of clinical development with a number of new product
candidates,  and  have  not  yet  generated  significant  revenues  from  our  approved  drug  products.  We  plan  on  submitting  our  clinical  trial  protocols  and
receiving approvals from the FDA and international regulatory authorities before we commence any clinical trials. We may not be successful in obtaining
acceptance from the FDA or comparable foreign regulatory authorities to start our clinical trials. If we do not obtain such acceptance, the time in which we
expect to commence clinical programs for any product candidate will be extended and such extension will increase our expenses and increase our need for
additional  capital.  Moreover,  there  is  no  guarantee  that  our  clinical  trials  will  be  successful  or  that  we  will  continue  clinical  development  in  support  of
additional product approvals from the FDA or comparable foreign regulatory authorities for any indication. We note that most product candidates never
reach the clinical development stage and even those that do commence clinical development have only a small chance of successfully completing clinical
development and gaining regulatory approval. Therefore, our business substantially depends entirely on the successful development, regulatory approval
and commercialization of our product candidates, which may never occur.

We face competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively.

The  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant  technological  change. We  have
existing competitors and potential new competitors in a number of jurisdictions, many of which have or will have substantially greater name recognition,
commercial infrastructures and financial, technical and personnel resources than we have. Established competitors may invest heavily to quickly discover
and  develop  novel  compounds  that  could  make  any  of  our  product  candidates  obsolete  or  uneconomical.  In  addition,  mergers  and  acquisitions  in  the
biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors, potentially
reducing or eliminating our commercial opportunity. Furthermore, such potential competitors may enter the market before us, and their products may be
designed to circumvent our pending patent applications and any patents we may receive. They may also challenge, narrow or invalidate any granted patents
or our patent applications, and such patents and patent applications may fail to provide adequate protection for our product candidates. Any new product
that  competes  with  an  approved  product  may  need  to  demonstrate  compelling  advantages  in  efficacy,  cost,  convenience,  tolerability  and  safety  to  be
commercially  successful.  Other  competitive  factors,  including  generic  competition,  could  force  us  to  lower  prices  or  could  result  in  reduced  sales.  In
addition, new products developed by others could emerge as competitors to our product candidates. If we are not able to compete effectively against our
current and future competitors, our business will not grow and our financial condition and operations will suffer.

We face substantial competition, which may result in others discovering, developing and commercializing products before or more successfully than
our product candidates.

The  development  and  commercialization  of  new  drugs  is  highly  competitive.  We  face  competition  (from  major  pharmaceutical  companies,
specialty  pharmaceutical  companies  and  biotechnology  companies  worldwide)  with  respect  to  our  current  product  candidates  and  will  face  competition
with respect to any product candidates that we may seek to develop or commercialize in the future. We compete directly with companies that focus on
505(b)(2)  and  generic  drugs,  and  companies  dedicating  their  resources  to  novel  forms  of  therapies  for  these  indications.  Many  of  these  competitors  are
attempting to develop products for our target indications. We face the risk that our competitors will develop a competing product using the same 505(b)(2)
pathway that we intend to pursue. Our business model is to focus on product candidates that we consider to have a shorter timeline to, and lower cost of,
regulatory approval. These attributes can also be taken advantage of by our competitors to develop and obtain marketing approval of a competing product.
In addition, following FDA approval of our product candidates for which we have no patent protection, our competitors may seek to develop a competing
product pursuant to the 505(j) pathway, which is an abbreviated pathway used for the regulatory approval of generic product candidates. As a result of the
foregoing, we may find that the market opportunity for our product candidates for which we have no patent protection is relatively small due to the fact that
barriers to entry are low and generic competition may follow within relatively short time periods after our product is approved. With the proliferation of
new drugs and therapies in these areas, we expect to face increasingly intense competition as new technologies become available. Any product candidates
that we successfully develop and commercialize will compete with existing products and new products that may become available in the future.

20

 
 
 
 
 
 
 
 
 
There are products already approved for all of the indications we are targeting. Many of these approved products are well established therapies and
are widely accepted by physicians, patients and third-party payors. This may make it difficult for us to achieve our business strategy of replacing existing
products with our product candidates. In addition, where we are able to offer benefits over existing products offered by our competitors, those competitors
may reformulate their drugs in a manner that mimics the benefits offered by our product candidates. As noted below, many of our product candidates are
not eligible for patent protection or the market and data exclusivity provisions under the Federal Food, Drug and Cosmetic Act (“FDCA”). Consequently,
our commercial operations face significant direct competition and our competitors may develop products that are similar to ours and perhaps safer, more
effective, more convenient or less costly than any that we are developing or that would render our product candidates obsolete or non-competitive. Our
inability to successfully compete could negatively impact our business, results of operations and stock price.

Our competitors may obtain FDA or other regulatory approval for comparable products more rapidly than we may obtain approval for ours, and the
risk of our competitors doing so may lead us to develop drug candidates without disclosing certain information with regard to such candidates.

The FDCA provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA, or supplement to an existing NDA or 505(b)(2) NDA if
new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to
the  approval  of  the  application,  (e.g.,  for  new  indications,  dosages,  strengths  or  dosage  forms  of  an  existing  drug).  Many  of  our  competitors  have
significantly  greater  financial,  manufacturing,  marketing,  drug  development,  technical  and  human  resources  than  we  do.  As  a  result,  many  of  our
competitors have the ability to bring a product candidate to market more rapidly than we can and depending on the nature of their product candidate they
could substantially delay the introduction of our product candidate into the market if their product qualifies for the market and data exclusivity provisions
under the FDCA. In order to preserve any competitive advantage, we will, at times, make the decision to pursue a product candidate for which we will not
disclose the API, dosage or reference drug until such time as we believe that any competitive advantage would not be materially compromised by public
disclosure of such information, which in some cases may be as late as our receipt of marketing approval from the FDA. Our business currently depends on
our  ability  to  bring  our  product  candidates  to  market  in  a  manner  that  preserves  our  perceived  competitive  advantage  and  any  loss  of  that  competitive
advantage could negatively impact our business, results of operations and stock price.

If we are not able to obtain any required regulatory approvals for our product candidates, we will not be able to commercialize our product candidate
and our ability to generate revenue will be limited.

We may be required to successfully complete clinical trials for our product candidates before we can apply for marketing approval. Even if we
complete any such clinical trials, it does not assure marketing approval. Any such clinical trials may be unsuccessful, which would materially harm our
business. Even if such initial clinical trials are successful, we may be required to conduct additional clinical trials to establish our product candidates’ safety
and efficacy, before an NDA or foreign equivalents can be submitted to the FDA or comparable foreign regulatory authorities for marketing approval of our
product candidates.

Our success depends on the receipt of regulatory approval and the issuance of such regulatory approvals is uncertain and subject to a number of

risks, including the following:

●

●

●

●

●

●

the results of any required toxicology studies may not support the submission of an IND for our product candidates;

the FDA or comparable foreign regulatory authorities or Institutional Review Boards (“IRB”), may disagree with the design or implementation
of our clinical trials;

we may not be able to provide acceptable evidence of our product candidates’ safety and efficacy;

the results of our clinical trials may not be satisfactory or may not meet the level of statistical or clinical significance required by the FDA or
other regulatory agencies for marketing approval;

the dosing of our product candidates in any required clinical trial may not be at an optimal level;

patients in our clinical trials may suffer adverse effects for reasons that may or may not be related to our product candidates;

●

the data collected from clinical trials may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory
approval in the United States or elsewhere;

the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes  or  facilities  of  third-party
manufacturers with which we contract for clinical and commercial supplies; and

the approval policies or regulations of the FDA may significantly change in a manner rendering our clinical data insufficient for approval.

Failure to obtain regulatory approval for our product candidates for the foregoing, or any other reasons, will prevent us from commercializing our
product  candidates,  and  our  ability  to  generate  sufficient  revenue  will  be  materially  impaired.  We  cannot  guarantee  that  regulators  will  agree  with  our
assessment of the results of the clinical trials we intend to conduct in the future or that such trials will be successful. The FDA and other regulators have
substantial discretion in the approval process and may refuse to accept any application or may decide that our data is insufficient for approval and require
additional clinical trials, or pre-clinical or other studies. In addition, varying interpretations of the data obtained from pre-clinical and clinical testing could
delay, limit or prevent regulatory approval of our product candidates.

The process of obtaining regulatory approvals is expensive, often takes many years, if approval is obtained at all, and can vary substantially based
upon, among other things, the type, complexity and novelty of the product candidates involved, the jurisdiction in which regulatory approval is sought and
the substantial discretion of the regulatory authorities. Changes in regulatory approval policies during the development period, changes in or the enactment
of additional statutes or regulations, or changes in regulatory review for a submitted product application may cause delays in the approval or rejection of an
application.  Regulatory  approval  obtained  in  one  jurisdiction  does  not  necessarily  mean  that  a  product  candidate  will  receive  regulatory  approval  in  all
jurisdictions in which we may seek approval, but the failure to obtain approval in one jurisdiction may negatively impact our ability to seek approval in a
different  jurisdiction.  Failure  to  obtain  regulatory  marketing  approval  for  our  product  candidates  will  prevent  us  from  commercializing  the  product
candidate, and our ability to generate sufficient revenue will be materially impaired.

If  the  FDA  does  not  conclude  that  our  product  candidates  satisfy  the  requirements  for  the  505(b)(2)  regulatory  approval  pathway,  or  if  the
requirements  for  approval  of  any  of  our  product  candidates  under  Section  505(b)(2)  are  not  as  we  expect,  the  approval  pathway  for  our  product
candidates will likely take significantly longer, cost significantly more and encounter significantly greater complications and risks than anticipated, and
in any case may not be successful.

We  intend  to  seek  FDA  approval  through  the  505(b)(2)  regulatory  pathway  for  the  majority  of  our  product  candidates.  The  Drug  Price
Competition  and  Patent  Term  Restoration  Act  of  1984,  also  known  as  the  Hatch-Waxman  Act,  added  Section  505(b)(2)  to  the  Federal  Food,  Drug  and
Cosmetic Act (“FDCA”). Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies
that were not conducted by or for the applicant. If the FDA does not allow us to pursue the 505(b)(2) regulatory pathway for our product candidates as
anticipated,  we  may  need  to  conduct  additional  clinical  trials,  provide  additional  data  and  information  and  meet  additional  standards  for  regulatory
approval.  If  this  were  to  occur,  the  time  and  financial  resources  required  to  obtain  FDA  approval  for  our  product  candidates  would  likely  substantially
increase. Moreover, the inability to pursue the 505(b)(2) regulatory pathway could result in new competitive products reaching the market faster than our
product  candidates,  which  could  materially  adversely  impact  our  competitive  position  and  prospects.  Even  if  we  are  allowed  to  pursue  the  505(b)(2)
regulatory  pathway  for  a  product  candidate,  we  cannot  assure  you  that  we  will  receive  the  requisite  or  timely  approvals  for  commercialization  of  such
product candidate. For example, we had under development a patented injectable pentoxifylline therapeutic candidate, which we believed would satisfy the
requirements  of  the  505(b)(2)  regulatory  pathway.  However,  based  on  a  pre-IND  meeting  with  the  FDA  in  March  2018  to  discuss  the  clinical  and
regulatory pathway for the product, we have decided to suspend all further development activities for this candidate indefinitely due to extraordinarily high
costs of the clinical trials that would be required by the FDA.

Notwithstanding  the  approval  of  many  products  by  the  FDA  pursuant  to  Section  505(b)(2),  over  the  last  few  years  some  pharmaceutical
companies  and  others  have  objected  to  the  FDA’s  interpretation  of  Section  505(b)(2)  to  allow  reliance  on  the  FDA’s  prior  findings  of  safety  and
effectiveness. If the FDA changes its interpretation of Section 505(b)(2), or if the FDA’s interpretation is successfully challenged in court, this could delay
or even prevent the FDA from approving any Section 505(b)(2) application that we submit. In addition, we expect that our competitors will file citizens’
petitions  with  the  FDA  in  an  attempt  to  persuade  the  FDA  that  our  product  candidate,  or  the  clinical  studies  that  support  their  approval,  contain
deficiencies. Such actions by our competitors could delay or even prevent the FDA from approving any NDA that we submit under Section 505(b)(2).

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Moreover, the FDA recently adopted an interpretation of the three-year exclusivity provisions whereby a 505(b)(2) application can be blocked by
exclusivity  even  if  does  not  rely  on  the  previously  approved  drug  that  has  exclusivity  (or  any  safety  or  effectiveness  information  regarding  that  drug).
Under the FDA’s new interpretation, approval may be blocked by exclusivity awarded to a previously-approved drug product that shares certain innovative
features with our product, even if our 505(b)(2) application does not identify the previously-approved drug product as a listed drug or rely upon any of its
safety  or  efficacy  data.  Any  failure  to  obtain  regulatory  approval  of  our  product  candidates  would  significantly  limit  our  ability  to  generate  sufficient
revenues, and any failure to obtain such approval for all of the indications and labeling claims we deem desirable could reduce our potential revenues.

An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or prevent
the review or approval of our product candidate.

The  505(b)(2)  application  would  enable  us  to  reference  published  literature  or  the  FDA’s  previous  findings  of  safety  and  effectiveness  for  the
branded reference drug. For NDAs submitted under Section 505(b)(2) of the FDCA, the patent certification and related provisions of the Hatch-Waxman
Act apply. In accordance with Hatch-Waxman Act, in seeking approval for a drug through such an NDA, applicants are required to list with the FDA each
patent whose claims cover the applicant’s product. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the
FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in
turn, be cited by potential generic competitors in support of approval of an ANDA. An ANDA provides for marketing of a drug product that has the same
active  ingredients  in  the  same  strengths  and  dosage  form  as  the  listed  drug  and  has  been  shown  to  be  bioequivalent  to  the  listed  drug.  Other  than  the
requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, pre-clinical or clinical tests to prove the safety
or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug and can often be
substituted by pharmacists under prescriptions written for the original listed drug.

The  ANDA  applicant  is  required  to  certify  to  the  FDA  concerning  any  patents  listed  for  the  approved  product  in  the  FDA’s  Orange  Book.
Specifically, the applicant must certify that either: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed
patent has not expired, but will expire on a particular date and approval is sought after patent expiration or (iv) the listed patent is invalid or will not be
infringed by the new product. The ANDA applicant may also elect to submit a section viii statement certifying that its proposed ANDA label does not
contain (or carves out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent. If the applicant does not
challenge the listed patents, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired.

A  certification  that  the  new  product  will  not  infringe  the  already  approved  product’s  listed  patents,  or  that  such  patents  are  invalid  or
unenforceable, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also
send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent
holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. Under the Hatch-Waxman Act, the holder
of patents that the 505 (b)(2) application references may file a patent infringement lawsuit after receiving notice of the Paragraph IV certification. Filing of
a  patent  infringement  lawsuit  against  the  filer  of  the  505(b)(2)  applicant  within  45  days  of  the  patent  owner’s  receipt  of  notice  triggers  a  one-time,
automatic, 30-month stay of the FDA’s ability to approve the 505(b)(2) NDA, unless patent litigation is resolved in favor of the Paragraph IV filer or the
patent expires before that time. Accordingly, we may invest a significant amount of time and expense in the development of one or more product candidates
only to be subject to significant delay and patent litigation before such product candidates may be commercialized, if at all.

In  addition,  a  505(b)(2)  application  will  not  be  approved  until  any  non-patent  exclusivity,  such  as  exclusivity  for  obtaining  approval  of  a  new
chemical entity listed in the Orange Book for the referenced product has expired. The FDA may also require us to perform one or more additional clinical
studies  or  measurements  to  support  the  change  from  the  branded  reference  drug,  which  could  be  time  consuming  and  could  substantially  delay  our
achievement of regulatory approvals for such product candidates. The FDA may also reject our future 505(b)(2) submissions and require us to file such
submissions under Section 505(b)(1) of the FDCA, which would require us to provide extensive data to establish safety and effectiveness of the drug for
the proposed use and could cause delay and be considerably more expensive and time consuming. These factors, among others, may limit our ability to
successfully commercialize our product candidates.

23

 
 
 
 
 
 
 
 
Companies that produce branded reference drugs routinely bring litigation against ANDA or 505(b)(2) applicants that seek regulatory approval to
manufacture and market generic and reformulated forms of their branded products. These companies often allege patent infringement or other violations of
intellectual property rights as the basis for filing suit against an ANDA or 505(b)(2) applicant. Likewise, patent holders may bring patent infringement suits
against  companies  that  are  currently  marketing  and  selling  their  approved  generic  or  reformulated  products.  Litigation  to  enforce  or  defend  intellectual
property rights is often complex and often involves significant expense and can delay or prevent introduction or sale of our product candidates. If patents
are held to be valid and infringed by our product candidates in a particular jurisdiction, we would, unless we could obtain a license from the patent holder,
be required to cease selling in that jurisdiction and may need to relinquish or destroy existing stock in that jurisdiction. There may also be situations where
we use our business judgment and decide to market and sell our approved products, notwithstanding the fact that allegations of patent infringement(s) have
not  been  finally  resolved  by  the  courts,  which  is  known  as  an  “at-risk  launch.”  The  risk  involved  in  doing  so  can  be  substantial  because  the  remedies
available to the owner of a patent for infringement may include, among other things, damages measured by the profits lost by the patent owner and not
necessarily by the profits earned by the infringer. In the case of a willful infringement, the definition of which is subjective, such damages may be increased
up  to  three  times.  Moreover,  because  of  the  discount  pricing  typically  involved  with  bioequivalent  and,  to  a  lesser  extent,  505(b)(2)  products,  patented
branded  products  generally  realize  a  substantially  higher  profit  margin  than  bioequivalent  and,  to  a  lesser  extent,  505(b)(2)  products,  resulting  in
disproportionate damages compared to any profits earned by the infringer. An adverse decision in patent litigation could have a material adverse effect on
our business, financial position and results of operations and could cause the market value of our common stock to decline.

Even if we receive regulatory approval for our additional product candidates, we may not be able to successfully commercialize these products, and the
revenue that we generate from those sales, if any, may be limited.

If  approved  for  marketing,  the  commercial  success  of  our  product  candidates  will  depend  upon  each  product’s  acceptance  by  the  medical
community, including physicians, patients and health care payors. The degree of market acceptance for any of our product candidates will depend on a
number of factors, including:

●

●

●

●

●

●

●

●

●

●

●

●

●

demonstration of clinical safety and efficacy;

relative convenience, dosing burden and ease of administration;

the prevalence and severity of any adverse effects;

the willingness of physicians to prescribe our product candidates, and the target patient population to try new therapies;

efficacy of our product candidates compared to competing products;

the introduction of any new products that may in the future become available targeting indications for which our product candidates may be
approved;

new procedures or therapies that may reduce the incidences of any of the indications in which our product candidates may show utility;

pricing and cost-effectiveness;

the inclusion or omission of our product candidates in applicable therapeutic and vaccine guidelines;

the effectiveness of our own or any future collaborators’ sales and marketing strategies;

limitations or warnings contained in approved labeling from regulatory authorities;

our  ability  to  obtain  and  maintain  sufficient  third-party  coverage  and  adequate  reimbursement  from  government  health  care  programs,
including  Medicare  and  Medicaid,  private  health  insurers  and  other  third-party  payors  or  to  receive  the  necessary  pricing  approvals  from
government bodies regulating the pricing and usage of therapeutics; and

the  willingness  of  patients  to  pay  out-of-pocket  in  the  absence  of  third-party  coverage  or  adequate  reimbursement  or  government  pricing
approvals.

If any of our product candidates are approved, but do not achieve an adequate level of acceptance by physicians, health care payors, and patients,
we may not generate sufficient revenue and we may not be able to achieve or sustain profitability. Our efforts to educate the medical community and third-
party payors on the benefits of our product candidates may require significant resources and may never be successful.

In addition, even if we obtain regulatory approvals for our product candidates, the timing or scope of any approvals may prohibit or reduce our
ability to commercialize our product candidates successfully. For example, if the approval process takes too long, we may miss market opportunities and
give  other  companies  the  ability  to  develop  competing  products  or  establish  market  dominance. Any  regulatory  approval  we  ultimately  obtain  may  be
limited  or  subject  to  restrictions  or  post-approval  commitments  that  render  our  product  candidates  not  commercially  viable.  For  example,  regulatory
authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge
for any of our product candidates, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve any of our
product  candidates  with  a  label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that  indication.
Further, the FDA or comparable foreign regulatory authorities may place conditions on approvals or require risk management plans or a Risk Evaluation
and Mitigation Strategy (“REMS”), to assure the safe use of the drug. If the FDA concludes a REMS is needed, the FDA will not approve the NDA without
an  approved  REMS,  if  required.  A  REMS  could  include  medication  guides,  physician  communication  plans  or  elements  to  assure  safe  use,  such  as
restricted distribution methods, patient registries and other risk minimization tools. The FDA may also require a REMS for an approved product when new
safety  information  emerges.  Any  of  these  limitations  on  approval  or  marketing  could  restrict  the  commercial  promotion,  distribution,  prescription  or
dispensing of our product candidates. Moreover, product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur
following the initial marketing of the product. Any of the foregoing scenarios could materially harm the commercial success of our product candidates.

We are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product
candidates could be subject to labeling and other restrictions and withdrawal from the market and we may be subject to penalties if we fail to comply
with regulatory requirements or if we experience unanticipated problems with our product candidates.

The FDA or foreign equivalent may still impose significant restrictions on our products indicated uses or the conditions of approval, or impose
ongoing  requirements  for  potentially  costly  and  time-consuming  post-approval  studies,  including  Phase  4  clinical  trials,  and  post-market  surveillance  to
monitor  safety  and  efficacy.  Our  product  candidates  will  also  be  subject  to  ongoing  regulatory  requirements  governing  the  manufacturing,  labeling,
packaging,  storage,  distribution,  safety  surveillance,  advertising,  promotion,  recordkeeping  and  reporting  of  adverse  events  and  other  post-market
information.  These  requirements  include  registration  with  the  FDA,  as  well  as  continued  compliance  with  current  Good  Clinical  Practices  regulations
(“cGCPs”)  for  any  clinical  trials  that  we  conduct  post-approval.  In  addition,  manufacturers  of  drug  products  and  their  facilities  are  subject  to  continual
review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirements relating to quality control, quality
assurance and corresponding maintenance of records and documents.

The FDA has the authority to require a REMS as part of an NDA or after approval, which may impose further requirements or restrictions on the
distribution  or  use  of  an  approved  drug,  such  as  limiting  prescribing  to  certain  physicians  or  medical  centers  that  have  undergone  specialized  training,
limiting treatment to patients who meet certain safe-use criteria or requiring patient testing, monitoring and/or enrollment in a registry.

With respect to sales and marketing activities by us or any future partner, advertising and promotional materials must comply with FDA rules in
addition to other applicable federal, state and local laws in the United States and similar legal requirements in other countries. In the United States, the
distribution of product samples to physicians must comply with the requirements of the U.S. Prescription Drug Marketing Act. Application holders must
obtain FDA approval for product and manufacturing changes, depending on the nature of the change. We may also be subject, directly or indirectly through
our  customers  and  partners,  to  various  fraud  and  abuse  laws,  including,  without  limitation,  the  U.S.  Anti-Kickback  Statute,  U.S.  False  Claims  Act,  and
similar state laws, which impact, among other things, our proposed sales, marketing and scientific/educational grant programs. If we participate in the U.S.
Medicaid Drug Rebate Program, the Federal Supply Schedule of the U.S. Department of Veterans Affairs, or other government drug programs, we will be
subject to complex laws and regulations regarding reporting and payment obligations. All of these activities are also potentially subject to U.S. federal and
state consumer protection and unfair competition laws. Similar requirements exist in many of these areas in other countries.

25

 
 
 
 
 
 
 
 
In addition, if any of our product candidates are approved for a particular indication, our product labeling, advertising and promotion would be
subject  to  regulatory  requirements  and  continuing  regulatory  review.  The  FDA  strictly  regulates  the  promotional  claims  that  may  be  made  about
prescription  products.  In  particular,  a  product  may  not  be  promoted  for  uses  that  are  not  approved  by  the  FDA  as  reflected  in  the  product’s  approved
labeling. However, companies may share truthful and not misleading information that is otherwise consistent with the product’s approved FDA labeling. If
we receive marketing approval for our product candidates, physicians may nevertheless legally prescribe our products to their patients in a manner that is
inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability and government
fines. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to
have improperly promoted off-label uses may be subject to significant sanctions. The federal government has levied large civil and criminal fines against
companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that
companies enter into consent decrees of permanent injunctions under which specified promotional conduct is changed or curtailed.

If  we  or  a  regulatory  agency  discovers  previously  unknown  problems  with  a  product,  such  as  adverse  events  of  unanticipated  severity  or
frequency,  problems  with  the  facility  where  the  product  is  manufactured,  or  we  or  our  manufacturers  fail  to  comply  with  applicable  regulatory
requirements, we may be subject to the following administrative or judicial sanctions:

●

●

●

●

●

●

●

●

●

restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product
recalls;

issuance of warning letters or untitled letters;

clinical holds;

injunctions or the imposition of civil or criminal penalties or monetary fines;

suspension or withdrawal of regulatory approval;

suspension of any ongoing clinical trials;

refusal to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license
approvals;

suspension or imposition of restrictions on operations, including costly new manufacturing requirements; or

product seizure or detention or refusal to permit the import or export of product.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue.

Adverse regulatory action, whether pre- or post-approval, can also potentially lead to product liability claims and increase our product liability exposure.

Obtaining  foreign  regulatory  approvals  and  compliance  with  foreign  regulatory  requirements  could  result  in  significant  delays,  difficulties  and
costs  for  us  and  could  delay  or  prevent  the  introduction  of  our  products  in  certain  countries.  If  we  fail  to  comply  with  the  regulatory  requirements  in
international markets and/or to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential
of our product candidates will be harmed.

Significant additional labeling or warning requirements or limitations on the availability of our products may inhibit sales of affected products.

Various jurisdictions may seek to adopt significant additional product labeling or warning requirements or limitations on the availability of our
products relating to the content or perceived adverse health consequences of our products. Federal laws may preempt some or all of these attempts by state
or localities to impose additional labeling or warning requirements. If these types of requirements become applicable to our products under current or future
environmental or health laws or regulations, they may inhibit sales of our products. Moreover, if we fail to meet compliance deadlines for any such new
requirements,  our  products  may  be  deemed  misbranded  or  mislabeled  and  could  be  subject  to  enforcement  action,  or  we  could  be  exposed  to  private
lawsuits alleging misleading labels or product promotion.

Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates
and affect the prices we may obtain.

In  the  United  States  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes
regarding the health care system that could prevent or delay marketing approval for our product candidates, restrict or regulate post-approval activities and
affect our ability to profitably sell our product candidates. Legislative and regulatory proposals have been made to expand post-approval requirements and
restrict sales and promotional activities for pharmaceutical products. We do not know whether additional legislative changes will be enacted, or whether the
FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if
any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as
well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In the United States, the Medicare Modernization Act (“MMA”) changed the way Medicare covers and pays for pharmaceutical products. The
legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices
for drugs. In addition, this legislation authorized Medicare Part D prescription drug plans to use formularies where they can limit the number of drugs that
will be covered in any therapeutic class. As a result of this legislation and the expansion of federal coverage of drug products, we expect that there will be
additional pressure to contain and reduce costs. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and
price  that  we  receive  for  our  product  candidates  and  could  seriously  harm  our  business.  While  the  MMA  applies  only  to  drug  benefits  for  Medicare
beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in
reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively
referred to as the Health Care Reform Law, was enacted, which substantially changes the way health care is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. The Health Care Reform Law, among other things, imposed reporting requirements on
manufacturers related to drug samples and financial relationships with physicians and teaching hospitals, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations,
established annual fees on manufacturers of certain branded prescription drugs, and established a Medicare Part D coverage gap discount program.

Some of the provisions of the Health Care Reform Law have yet to be implemented, and there have been judicial and Congressional challenges to
certain aspects of the Health Care Reform Law, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the Health Care
Reform Law. Since January 2017, former President Trump had signed two executive orders and other directives designed to delay, circumvent or loosen
certain requirements mandated by the Health Care Reform Law. Concurrently, Congress has considered legislation that would repeal or repeal and replace
all  or  part  of  the  Health  Care  Reform  Law.  While  Congress  has  not  passed  comprehensive  repeal  legislation,  two  bills  affecting  the  implementation  of
certain taxes under the Health Care Reform Law have been signed into law. The Tax Act included a provision which repealed, effective January 1, 2019,
the  tax-based  shared  responsibility  payment  imposed  by  the  Health  Care  Reform  Law  on  certain  individuals  who  fail  to  maintain  qualifying  health
coverage  for  all  or  part  of  a  year  that  is  commonly  referred  to  as  the  “individual  mandate.”  On  January  22,  2018,  former  President  Trump  signed  a
continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Health Care Reform Law-mandated fees, including
the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based
on market share, and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, among other things, amended the
Health Care Reform, effective January 1, 2019, to increase from 50% to 70% the point-of-sale discount that is owed by pharmaceutical manufacturers who
participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. On December 14,
2018, a Texas U.S. District Court Judge ruled that the Health Care Reform is unconstitutional in its entirety because the “individual mandate” was repealed
by Congress as part of the Tax Act. While the Texas U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the ruling
will have no immediate effect pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the
Health  Care  Reform  will  impact  the  ACA  and  our  business.  We  cannot  predict  the  impact  on  our  business  of  changes  to  current  laws  and  regulations.
However, any changes that lower reimbursements for products for which we may obtain regulatory approval, or that impose administrative and financial
burdens on us, could adversely affect our business.

27

 
 
 
 
 
 
 
In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. These
changes include, among others, aggregate reductions of Medicare payments to providers of up to 2% per fiscal year. We expect that additional state and
federal health care reform measures will be adopted in the future, which may alter or completely replace the existing health care financing structure. Any of
these  reform  measures  could  limit  the  amounts  that  federal  and  state  governments  will  pay  for  health  care  products  and  services,  which  could  result  in
reduced demand for any such product candidate that we may have developed or additional pricing pressures on our business.

Further,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of  pharmaceutical  pricing  practices  in  light  of  the  rising  cost  of
prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for products. For example, the Trump administration released a “Blueprint” to lower drug
prices and reduce out of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power
of  certain  federal  healthcare  programs,  incentivize  manufacturers  to  lower  the  list  price  of  their  products,  and  reduce  the  out  of  pocket  costs  of  drug
products  paid  by  consumers.  On  January  31,  2019,  the  U.S.  Department  of  Health  and  Human  Services,  Office  of  Inspector  General,  proposed
modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among
other things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit
managers working with these organizations. While some of these and other proposed measures may require additional authorization to become effective,
Congress  and  government  administration  officials  have  each  indicated  that  they  will  continue  to  seek  new  legislative  and/or  administrative  measures  to
control drug costs.

The policies of the FDA or similar regulatory authorities may change, and additional government regulations may be enacted that could prevent,
limit or delay regulatory approval of our product candidates. For example, in December 2016, the 21st Century Cures Act was signed into law. The 21st
Century Cures Act, among other things, is intended to modernize the regulation of drugs and biologics and spur innovation, but it has not yet been fully
implemented and its ultimate implementation is unclear. Furthermore, the Trump administration has taken several executive actions, including the issuance
of a number of executive orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability to engage in routine regulatory
and  oversight  activities  such  as  implementing  statutes  through  rulemaking,  issuance  of  guidance  and  review  and  approval  of  marketing  applications.  If
these executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may
be negatively impacted. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are
not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve
or sustain profitability, which would adversely affect our business.

If we market our existing approved products or any of our new product candidates in a manner that violates health care fraud and abuse laws, or if we
violate government price reporting laws, we may be subject to civil or criminal penalties.

The FDA enforces laws and regulations, which require that the promotion of pharmaceutical products be consistent with the approved prescribing
information. While physicians may prescribe an approved product for a so-called “off label” use, it is unlawful for a pharmaceutical company to promote
its products in a manner that is inconsistent with its approved label and any company which engages in such conduct can be subject to significant liability.
Similarly,  industry  codes  in  the  EU  and  other  foreign  jurisdictions  prohibit  companies  from  engaging  in  off-label  promotion  and  regulatory  agencies  in
various countries enforce violations of the code with civil penalties. While we intend to ensure that our promotional materials are consistent with our label,
regulatory agencies may disagree with our assessment and may issue untitled letters, warning letters or may institute other civil or criminal enforcement
proceedings. In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal health care fraud and abuse
laws have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws include, among others, the U.S.
Anti-Kickback Statute, U.S. False Claims Act and similar state laws. Because of the breadth of these laws and the narrowness of their exceptions and safe
harbors, it is possible that some of our business activities could be subject to challenge under one or more of these laws.

28

 
 
 
 
 
 
 
The U.S. Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to
induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any health care item or service reimbursable under
Medicare,  Medicaid  or  other  federally  financed  health  care  programs.  This  statute  has  been  interpreted  broadly  to  apply  to  arrangements  between
pharmaceutical manufacturers on the one hand and prescribers, purchasers, formulary managers, and others on the other hand. Although there are several
statutory  exceptions  and  regulatory  safe  harbors  protecting  certain  common  activities  from  prosecution,  the  exceptions  and  safe  harbors  are  drawn
narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not
qualify for an exception or safe harbor. Our practices may not, in all cases, meet all of the criteria for safe harbor protection from anti-kickback liability.
Moreover, recent health care reform legislation has strengthened these laws. For example, the Health Care Reform Law, among other things, amended the
intent  requirement  of  the  U.S.  Anti-Kickback  Statute  and  other  criminal  health  care  fraud  statutes;  a  person  or  entity  no  longer  needs  to  have  actual
knowledge of the statutes or specific intent to violate them in order to have committed a violation. In addition, the Health Care Reform Law provides that
the  government  may  assert  that  a  claim  including  items  or  services  resulting  from  a  violation  of  the  U.S.  Anti-Kickback  Statute  constitutes  a  false  or
fraudulent  claim  for  purposes  of  the  U.S.  False  Claims Act.  Federal  false  claims  laws  prohibit  any  person  from  knowingly  presenting,  or  causing  to  be
presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement to get a false claim paid.

Over the past few years, several pharmaceutical and other health care companies have been prosecuted under these laws for a variety of alleged
promotional and marketing activities, such as: allegedly providing free trips, free goods, sham consulting fees and grants and other monetary benefits to
prescribers; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in
off-label  promotion  that  caused  claims  to  be  submitted  to  Medicare  or  Medicaid  for  non-covered,  off-label  uses;  and  submitting  inflated  best  price
information to the Medicaid Rebate Program to reduce liability for Medicaid rebates. Most states also have statutes or regulations similar to the U.S. Anti-
Kickback Statute and the U.S. False Claims Act, which apply to items and services reimbursed under Medicaid and other state programs, or, in several
states,  apply  regardless  of  the  payor.  Sanctions  under  these  federal  and  state  laws  may  include  significant  administrative,  criminal,  and  civil  monetary
penalties, exclusion of a manufacturer’s products from reimbursement under government programs, fines and imprisonment.

We are completely dependent on third parties to manufacture our approved products and new product candidates, and our commercialization of our
product  candidates  could  be  halted,  delayed  or  made  less  profitable  if  those  third  parties  fail  to  obtain  manufacturing  approval  from  the  FDA  or
comparable foreign regulatory authorities, fail to provide us with sufficient quantities of our product candidates or fail to do so at acceptable quality
levels or prices.

We do not currently have, nor do we plan to acquire, the capability or infrastructure to manufacture the active pharmaceutical ingredient (“API”)
in our product candidates for use in our clinical trials or for commercial product, if any. In addition, we do not have the capability to encapsulate any of our
product candidates as a finished drug product for commercial distribution. As a result, we will be obligated to rely on contract manufacturers, if and when
any of our product candidates are approved for commercialization. While we have entered into certain agreements with contract manufacturers for clinical
and commercial supply, there can be no assurance we will be able to maintain those relationships or engage additional contract manufacturers for clinical or
commercial supply of any of our product candidates on favorable terms to us, or at all.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  product  candidates  must  be  approved  by  the  FDA  or  comparable  foreign
regulatory authorities pursuant to inspections that will be conducted after we submit an NDA to the FDA or their equivalents to other relevant regulatory
authorities. We will not control the manufacturing process of, and will be completely dependent on, our contract manufacturing partners for compliance
with cGMPs for manufacture of both active drug substances and finished drug products. These cGMP regulations cover all aspects of the manufacturing,
testing, quality control and record keeping relating to our product candidates. If our contract manufacturers do not successfully manufacture material that
conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to secure or maintain regulatory approval
for  their  manufacturing  facilities.  If  the  FDA  or  a  comparable  foreign  regulatory  authority  does  not  approve  these  facilities  for  the  manufacture  of  our
product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly
impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved.

Our contract manufacturers will be subject to ongoing periodic unannounced inspections by the FDA and corresponding state and foreign agencies
for  compliance  with  cGMPs  and  similar  regulatory  requirements.  We  will  not  have  control  over  our  contract  manufacturers’  compliance  with  these
regulations and standards. Failure by any of our contract manufacturers to comply with applicable regulations could result in sanctions being imposed on
us, including fines, injunctions, civil penalties, failure to grant approval to market any of our product candidates, delays, suspensions or withdrawals of
approvals, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business. In addition, we will not have
control  over  the  ability  of  our  contract  manufacturers  to  maintain  adequate  quality  control,  quality  assurance  and  qualified  personnel.  Failure  by  our
contract manufacturers to comply with or maintain any of these standards could adversely affect our ability to develop, obtain regulatory approval for or
market any of our product candidates.

29

 
 
 
 
 
 
 
 
If, for any reason, these third parties are unable or unwilling to perform, we may not be able to terminate our agreements with them, and we may
not be able to locate alternative manufacturers or formulators or enter into favorable agreements with them and we cannot be certain that any such third
parties will have the manufacturing capacity to meet future requirements. If these manufacturers or any alternate manufacturer of finished drug product
experiences any significant difficulties in its respective manufacturing processes for our API or finished products or should cease doing business with us,
we could experience significant interruptions in the supply of any of our product candidates or may not be able to create a supply of our product candidates
at all. Were we to encounter manufacturing issues, our ability to produce a sufficient supply of any of our product candidates might be negatively affected.
Our inability to coordinate the efforts of our third-party manufacturing partners, or the lack of capacity available at our third-party manufacturing partners,
could impair our ability to supply any of our product candidates at required levels. Because of the significant regulatory requirements that we would need
to satisfy in order to qualify a new bulk or finished product manufacturer, if we face these or other difficulties with our current manufacturing partners, we
could experience significant interruptions in the supply of any of our product candidates if we decided to transfer the manufacture of any of our product
candidates to one or more alternative manufacturers in an effort to deal with the difficulties.

Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in lost sales. Additionally, we
rely  on  third  parties  to  supply  the  raw  materials  needed  to  manufacture  our  potential  products.  Any  reliance  on  suppliers  may  involve  several  risks,
including  a  potential  inability  to  obtain  critical  materials  and  reduced  control  over  production  costs,  delivery  schedules,  reliability  and  quality.  Any
unanticipated disruption to a contract manufacturer caused by problems at suppliers could delay shipment of Biorphen or any of our product candidates,
increase our cost of goods sold and result in lost sales.

We cannot guarantee that our future manufacturing and supply partners will be able to reduce the costs of commercial scale manufacturing of any
of our product candidates over time. If the commercial-scale manufacturing costs of any of our product candidates are higher than expected, these costs
may significantly impact our operating results. In order to reduce costs, we may need to develop and implement process improvements. However, in order
to do so, we will need, from time to time, to notify or make submissions with regulatory authorities, and the improvements may be subject to approval by
such regulatory authorities. We cannot be sure that we will receive these necessary approvals or that these approvals will be granted in a timely fashion. We
also cannot guarantee that we will be able to enhance and optimize output in our commercial manufacturing process. If we cannot enhance and optimize
output, we may not be able to reduce our costs over time.

We may not be able to establish agreements with third parties with whom we wish to collaborate and, if we are able to establish them, we may not be
able to establish them on commercially reasonable terms, which could result in alterations or delays of our development and commercialization plans.

We face significant competition in seeking appropriate third parties. Whether we reach a definitive agreement will depend, among other things,
upon our assessment of the third parties’ resources and expertise, the terms and conditions of the proposed agreement, and the proposed parties’ evaluation
of  a  number  of  factors.  Those  factors  may  include  the  design  or  results  of  clinical  trials,  the  likelihood  of  approval  by  the  FDA  or  similar  regulatory
authorities outside the United States, the potential market for the product candidate, the costs and complexities of manufacturing and delivering the product
candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there
is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. Potential third parties may also
consider  alternative  product  candidates  or  technologies  for  similar  indications  that  may  be  available  to  collaborate  on  and  whether  such  a  collaboration
could be more attractive than the one with us for our product candidate. The terms of any arrangements that we may establish may also not be favorable to
us.

Agreements with third parties are complex and time-consuming to negotiate and document. In addition, there have been a significant number of
recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future third parties. We may not
be able to negotiate agreements on a timely basis, on acceptable terms or at all. If we are unable to do so, we may have to curtail the development of the
product candidate, reduce or delay its development program, delay its potential commercialization or reduce the scope of any sales or marketing activities,
or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to
fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable
terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidate or bring it to market and generate product
revenue.

30

 
 
 
 
 
 
 
 
In addition, any future agreements that we enter into may not be successful. The success of our arrangements will depend heavily on the efforts
and  activities  of  our  third-party  collaborators.  Collaborators  generally  have  significant  discretion  in  determining  the  efforts  and  resources  that  they  will
apply to these collaborations. Disagreements between parties to an agreement regarding clinical development and commercialization matters can lead to
delays  in  the  development  process  or  commercializing  the  applicable  product  candidate  and,  in  some  cases,  termination  of  the  agreement.  These
disagreements can be difficult to resolve if neither of the parties has final decision-making authority. Collaborations with pharmaceutical or biotechnology
companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration would adversely affect us
financially and could harm our business reputation.

We may need to rely on third parties to conduct clinical trials for our future product candidates. If these third parties do not successfully carry out their
contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize any of our product candidates
and our business would be substantially harmed.

We have entered into agreements with third-party CROs to conduct and manage our clinical programs including contracting with clinical sites to
perform  our  clinical  studies.  We  plan  to  rely  heavily  on  these  parties  for  execution  of  clinical  studies  for  our  product  candidates  and  will  control  only
certain aspects of their activities. Nevertheless, we will be responsible for ensuring that each of our studies is conducted in accordance with the applicable
protocol, legal, regulatory and scientific standards, and our reliance on CROs and clinical sites will not relieve us of our regulatory responsibilities. We and
our CROs will be required to comply with cGCPs, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities
for  any  products  in  clinical  development.  The  FDA  and  its  foreign  equivalents  enforce  these  cGCP  regulations  through  periodic  inspections  of  trial
sponsors, principal investigators and trial sites. If we or our CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials
may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving
our marketing applications. We cannot assure you that, upon inspection, the FDA or other regulatory authorities will determine that any of our clinical trials
comply with cGCPs. In addition, our clinical trials must be conducted with products produced under cGMP regulations and will require a large number of
test subjects. Our failure or the failure of our CROs or clinical sites to comply with these regulations may require us to repeat clinical trials, which would
delay the regulatory approval process and could also subject us to enforcement action up to and including civil and criminal penalties.

Although we intend to design the clinical trials for our product candidates in consultation with CROs, we expect that the CROs will manage all of
the clinical trials conducted at contracted clinical sites. As a result, many important aspects of our drug development programs would be outside of our
direct control. In addition, the CROs and clinical sites may not perform all of their obligations under arrangements with us or in compliance with regulatory
requirements.  If  the  CROs  or  clinical  sites  do  not  perform  clinical  trials  in  a  satisfactory  manner,  breach  their  obligations  to  us  or  fail  to  comply  with
regulatory  requirements,  the  development  and  commercialization  of  any  of  our  product  candidates  for  the  subject  indication  may  be  delayed  or  our
development program materially and irreversibly harmed. We cannot control the amount and timing of resources these CROs and clinical sites will devote
to our program or any of our product candidates. If we are unable to rely on clinical data collected by our CROs, we could be required to repeat, extend the
duration of, or increase the size of our clinical trials, which could significantly delay commercialization and require significantly greater expenditures.

If any of our relationships with these third-party CROs or clinical sites terminate, we may not be able to enter into arrangements with alternative
CROs or clinical sites. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced
or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or
for other reasons, any such clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully
commercialize our product candidates. As a result, our financial results and the commercial prospects for any of our product candidates would be harmed,
our costs could increase and our ability to generate revenue could be delayed.

We enter into various contracts in the normal course of our business, some or all of which may require us to indemnify the other party to the contract.
In the event we have to perform under these indemnification provisions, it could have an adverse effect on our business, financial condition and results
of operations.

In the normal course of business, we periodically may enter into commercial, service, collaboration, licensing, consulting and other agreements
that contain indemnification provisions. With respect to our commercial agreements, vendors typically ask for indemnification from any third-party product
liability  claims  that  could  result  from  the  production,  use  or  consumption  of  the  product,  as  well  as  for  alleged  infringements  of  any  patent  or  other
intellectual property right by a third party. Should our obligation under an indemnification provision exceed applicable insurance coverage or if we were
denied insurance coverage, our business, financial condition and results of operations could be adversely affected. Similarly, if we are relying on a third
party to indemnify us and the party is denied insurance coverage, or the indemnification obligation exceeds the applicable insurance coverage and does not
have other assets available to indemnify us, our business, financial condition and results of operations could be adversely affected.

31

 
 
 
 
 
 
 
 
 
Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product candidates for any
indications could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

The commencement and completion of clinical studies can be delayed for a number of reasons, including delays related to:

● the FDA or a comparable foreign regulatory authority failing to grant permission to proceed and placing the clinical study on hold;

● subjects for clinical testing failing to enroll or remain in our trials at the rate we expect;

● a facility manufacturing any of our product candidates being ordered by the FDA or other government or regulatory authorities to temporarily
or  permanently  shut  down  due  to  violations  of  cGMP  requirements  or  other  applicable  requirements,  or  cross-contaminations  of  product
candidates in the manufacturing process;

● any changes to our manufacturing process that may be necessary or desired;

● subjects  choosing  an  alternative  treatment  for  the  indications  for  which  we  are  developing  our  product  candidates,  or  participating  in

competing clinical studies;

● subjects experiencing severe or unexpected drug-related adverse effects;

● reports from clinical testing on similar technologies and products raising safety and/or efficacy concerns;

● third-party clinical investigators losing their license or permits necessary to perform our clinical trials, not performing our clinical trials on our
anticipated  schedule  or  employing  methods  consistent  with  the  clinical  trial  protocol,  cGMP  requirements,  or  other  third  parties  not
performing data collection and analysis in a timely or accurate manner;

● inspections of clinical study sites by the FDA, comparable foreign regulatory authorities, or IRBs finding regulatory violations that require us
to undertake corrective action, result in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study,
or that prohibit us from using some or all of the data in support of our marketing applications;

● third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for
violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or any
of the data produced by such contractors in support of our marketing applications;

● one or  more  IRBs  refusing  to  approve,  suspending  or  terminating  the  study  at  an  investigational  site,  precluding  enrollment  of  additional
subjects, or withdrawing its approval of the trial; reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the
terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

● deviations of the clinical sites from trial protocols or dropping out of a trial;

● adding new clinical trial sites;

● the inability of the CRO to execute any clinical trials for any reason; and

● government or regulatory delays or “clinical holds” requiring suspension or termination of a trial.

Product development costs for any of our product candidates will increase if we have delays in testing or approval or if we need to perform more
or larger clinical studies than planned. Additionally, changes in regulatory requirements and policies may occur and we may need to amend study protocols
to reflect these changes. Amendments may require us to resubmit our study protocols to the FDA, comparable foreign regulatory authorities, and IRBs for
reexamination, which may impact the costs, timing or successful completion of that study. If we experience delays in completion of, or if we, the FDA or
other regulatory authorities, the IRB, or other reviewing entities, or any of our clinical study sites suspend or terminate any of our clinical studies of any of
our product candidates, its commercial prospects may be materially harmed and our ability to generate sufficient product revenues will be delayed. Any
delays in completing our clinical trials will increase our costs, slow down our development and approval process and jeopardize our ability to generate
sufficient revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that
cause, or lead to, termination or suspension of, or a delay in the commencement or completion of, clinical studies may also ultimately lead to the denial of
regulatory approval of our product candidates. In addition, if one or more clinical studies are delayed, our competitors may be able to bring products to
market before we do, and the commercial viability of any of our product candidates could be significantly reduced.

Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be
predictive of future trial results.

Clinical testing of drug product candidates is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can
occur at any time during the clinical trial process. The results of pre-clinical studies and early clinical trials may not be predictive of the results of later-
stage clinical trials. We cannot assure you that the FDA or comparable foreign regulatory authorities will view the results as we do or that any future trials
of any of our product candidates will achieve positive results. Product candidates in later stages of clinical trials may fail to show the desired safety and
efficacy traits despite having progressed through pre-clinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry
have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier
trials. Any future clinical trial results for our product candidates may not be successful.

In addition, a number of factors could contribute to a lack of favorable safety and efficacy results for any of our product candidates. For example,
such  trials  could  result  in  increased  variability  due  to  varying  site  characteristics,  such  as  local  standards  of  care,  differences  in  evaluation  period  and
surgical technique, and due to varying patient characteristics including demographic factors and health status.

We may need to conduct clinical trials for our new product candidates and we may be delayed in commercializing or fail to find success in these
trials. Further, the results of any clinical trial may not be predictive of future trial results. Positive results in preclinical testing and early clinical trials do not
ensure that later clinical trials will be successful. A number of pharmaceutical companies have suffered significant setbacks in clinical trials, including in
Phase 3, after promising results in preclinical testing and early clinical trials. These setbacks have included negative safety and efficacy observations in
later clinical trials, including previously unreported adverse events.

Phase 3 clinical trials often produce unsatisfactory results even though prior clinical trials were successful. Moreover, the results of clinical trials
may be unsatisfactory to the FDA or foreign regulatory authorities even if we believe those clinical trials to be successful. The FDA or applicable foreign
regulatory agencies may suspend one or all of our clinical trials or require that we conduct additional clinical, nonclinical, manufacturing, validation or
drug product quality studies and submit that data before considering or reconsidering any NDA or similar foreign regulatory application we may submit.
Depending on the extent of these additional studies, approval of any applications that we submit may be significantly delayed or may require us to expend
more resources than we have available. It is also possible that additional studies we conduct may not be considered sufficient by the FDA or applicable
foreign regulatory agencies to provide regulatory approval.

If any of these outcomes occur, we may not receive approval for our product candidate.

33

 
 
 
 
 
 
 
 
 
Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.

Our  ability  to  successfully  market  Biorphen  and  our  product  candidates  will  depend  in  part  on  the  coverage  and  level  of  reimbursement  that
government  health  administration  authorities,  private  health  coverage  insurers  and  other  organizations  provide  for  the  cost  of  our  products  and  related
treatments. Countries in which any of our product candidates are sold through reimbursement schemes under national health insurance programs frequently
require  that  manufacturers  and  sellers  of  pharmaceutical  products  obtain  governmental  approval  of  initial  prices  and  any  subsequent  price  increases.  In
certain  countries,  including  the  United  States,  government-funded  and  private  medical  care  plans  can  exert  significant  indirect  pressure  on  prices.
Increasingly, third-party payors attempt to contain health care costs in ways that are likely to impact our development of products, including:

● failing to approve or challenging the prices charged for health care products;

● introducing reimportation schemes from lower priced jurisdictions;

● limiting both coverage and the amount of reimbursement for new therapeutic products;

● denying  or  limiting  coverage  for  products  that  are  approved  by  the  regulatory  agencies  but  are  considered  to  be  experimental  or

investigational by third-party payors; and

● refusing to provide coverage when an approved product is used in a way that has not received regulatory marketing approval.

We may not be able to sell Biorphen or our product candidates profitably if adequate prices are not approved or coverage and reimbursement is

unavailable or limited in scope.

We are subject to extensive laws and regulations related to data privacy, and our failure to comply with these laws and regulations could harm our
business.

We are subject to laws and regulations governing data privacy and the protection of personal information. These laws and regulations govern our
processing  of  personal  data,  including  the  collection,  access,  use,  analysis,  modification,  storage,  transfer,  security  breach  notification,  destruction  and
disposal of personal data. There are foreign and state law versions of these laws and regulations to which we are currently and/or may in the future, be
subject. For example, the collection and use of personal health data in the European Union is governed by the GDPR. The GDPR, which is wide-ranging in
scope,  imposes  several  requirements  relating  to  the  consent  of  the  individuals  to  whom  the  personal  data  relates,  the  information  provided  to  the
individuals,  the  security  and  confidentiality  of  the  personal  data,  data  breach  notification  and  the  use  of  third-party  processors  in  connection  with  the
processing of personal data. The GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States, provides
an enforcement authority and imposes large monetary penalties for noncompliance. The GDPR requirements apply not only to third-party transactions, but
also  to  transfers  of  information  within  our  company,  including  employee  information.  In  addition,  in  2018  California  adopted  a  new  privacy  law  that
became  effective  on  January  1,  2020,  which  borrows  heavily  from  the  GDPR.  The  GDPR  and  similar  data  privacy  laws  of  other  jurisdictions  place
significant responsibilities on us and create potential liability in relation to personal data that we or our third-party service providers process, including in
clinical trials conducted in the United States and the European Union. In addition, we expect that there will continue to be new proposed laws, regulations
and industry standards relating to privacy and data protection in the United States, the European Union and other jurisdictions, and we cannot determine the
impact such future laws, regulations and standards may have on our business.

Risks Relating to Our Intellectual Property Rights

We  will  depend  on  rights  to  certain  pharmaceutical  compounds  that  have  been  acquired  by  us.  We  do  not  have  complete  control  over  these
pharmaceutical compounds and any loss of our rights to them could prevent us from selling our products.

We  are  dependent  on  the  assignment  and  licensing  from  third  parties  for  certain  of  our  pharmaceutical  compounds  and  potential  product
candidates. Our rights to use the pharmaceutical compounds we were assigned are subject to the negotiation of, continuation of and compliance with the
terms of those assignments and licenses. Moreover, under these agreements, any related patents may remain under the control of the assignor or licensor.
Our rights to develop and commercialize the product candidates are subject to the validity of the intellectual property rights. Enforcement of any assigned
or licensed patents or defense or any claims asserting the invalidity of these patents is often subject to the control or cooperation of the assignor or licensor.
Legal action could be initiated against the original owners of the intellectual property that we acquired and an adverse outcome in such legal action could
harm our business because it might prevent such companies or institutions from continuing to assign intellectual property that we may need to operate our
business.

In addition, our rights to practice the inventions claimed in any patents and patent applications are subject to our assignors and licensors abiding
by the terms of those agreements and not terminating them. These agreements may be terminated by the assignor or licensor if we are in material breach of
certain terms or conditions of the agreement or in certain other circumstances. Our rights under these agreements are subject to our continued compliance
with the terms of the agreements, including the payment of royalties and other payment due under the agreements. Termination of these agreements could
prevent us from marketing some or all of our products. Because of the complexity of our products and the patents, determining the scope of the assignment
or license and related royalty obligations can be difficult and can lead to disputes between us and the assignor or licensor. An unfavorable resolution of
such a dispute could lead to an increase in the royalties payable pursuant to the agreement. If the assignor or licensor believed we were not paying the
royalties due under the agreement or were otherwise not in compliance with the terms of the agreement, the assignor or licensor might attempt to revoke the
agreement. If such an attempt were successful, we might be barred from producing and selling some or all of our products.

It may be difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.

Our  commercial  success  will  depend,  in  part,  on  obtaining  and  maintaining  patent  protection  for  our  technologies,  products  and  processes,
successfully  defending  these  patents  against  third-party  challenges  and  successfully  enforcing  these  patents  against  third-party  competitors.  The  patent
positions  of  pharmaceutical  companies  can  be  highly  uncertain  and  involve  complex  legal,  scientific  and  factual  questions  for  which  important  legal
principles  remain  unresolved.  Changes  in  either  the  patent  laws  or  in  interpretations  of  patent  laws  may  diminish  the  value  of  our  intellectual  property.
Accordingly, we cannot predict the breadth of claims that may be allowable or enforceable in our patents. Patent and patent applications relating to our
product candidates and related technologies may be challenged, invalidated or circumvented by third parties and might not protect us against competitors
with similar products or technologies.

The degree of future protection for our proprietary rights is uncertain, because legal means afford only limited protection and may not adequately
protect our rights, permit us to gain or keep our competitive advantage, or provide us with any competitive advantage at all. For example, others have filed,
and in the future are likely to file, patent applications covering products and technologies that are similar, identical or competitive to any of our product
candidates,  or  important  to  our  business.  We  cannot  be  certain  that  any  patent  application  owned  by  a  third  party  will  not  have  priority  over  patent
applications filed by us, or that we will not be involved in interference, opposition or invalidity proceedings before U.S. or foreign patent offices.

Additionally,  if  we  or  one  of  our  licensing  partners  initiated  legal  proceedings  against  a  third  party  to  enforce  a  patent  covering  any  product
candidate, the defendant could counterclaim that the patent covering any other product candidate is invalid and/or unenforceable. In patent litigation in the
United  States,  defendant  counterclaims  alleging  invalidity  and/or  unenforceability  are  commonplace.  Grounds  for  a  validity  challenge  include  alleged
failures to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Grounds for unenforceability assertions
include allegations that someone connected with prosecution of the patent withheld relevant information from the U.S. Patent and Trademark Office (“U.S.
PTO”), or made a misleading statement, during prosecution. Third parties may also raise similar claims before administrative bodies in the United States or
abroad,  even  outside  the  context  of  litigation.  Such  mechanisms  include  re-examination,  post  grant  review  and  equivalent  proceedings  in  foreign
jurisdictions, e.g. opposition proceedings. Such proceedings could result in revocation or amendment of our patents or our licensors’ patents in such a way
that  they  no  longer  cover  product  candidates  or  competitive  products.  The  outcome  following  legal  assertions  of  invalidity  and  unenforceability  is
unpredictable. With respect to validity, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were
unaware  during  prosecution.  If  a  defendant  were  to  prevail  on  a  legal  assertion  of  invalidity  and/or  unenforceability,  we  would  lose  at  least  part,  and
perhaps all, of the patent protection on any product candidate. Such a loss of patent protection would have a material adverse impact on our business.

In  the  future,  we  may  rely  on  know-how  and  trade  secrets  to  protect  technology,  especially  in  cases  when  we  believe  patent  protection  is  not
appropriate or obtainable. However, know-how and trade secrets are difficult to protect. While we intend to require employees, academic collaborators,
consultants and other contractors to enter into confidentiality agreements, we may not be able to adequately protect our trade secrets or other proprietary or
licensed information. Typically, research collaborators and scientific advisors have rights to publish data and information in which we may have rights. If
we cannot maintain the confidentiality of our proprietary technology and other confidential information, our ability to receive patent protection and our
ability to protect valuable information owned by us may be imperiled. Enforcing a claim that a third-party entity illegally obtained and is using any of our
trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts are sometimes less willing to protect trade secrets than
patents. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

We may not be able to protect our intellectual property rights throughout the world.

Filing,  prosecuting  and  defending  patents  on  product  candidates  in  all  countries  and  jurisdictions  throughout  the  world  would  be  prohibitively
expensive, and our intellectual property rights in some countries outside the United States could be less extensive than those offered in the United States.
Consequently,  we  may  not  be  able  to  prevent  third  parties  from  practicing  our  inventions  in  all  countries  outside  the  United  States,  or  from  selling  or
importing products made using our inventions in and into the United States or other jurisdictions.

Competitors may use our technologies in jurisdictions where we do not have, or where we do not pursue and obtain, patent protection to develop
their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as
that  in  the  United  States.  These  products  may  compete  with  our  product  and  our  patents  or  other  intellectual  property  rights  may  not  be  effective  or
sufficient to prevent them from competing. Even if we pursue and obtain issued patents in particular jurisdictions, our patent claims or other intellectual
property rights may not be effective or sufficient to prevent third parties from so competing.

Further, the laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many
companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems
of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those
relating  to  biotechnology.  This  could  make  it  difficult  for  us  to  stop  the  infringement  of  our  patents,  if  obtained,  or  the  misappropriation  of  our  other
intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third
parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In
these  countries,  patents  may  provide  limited  or  no  benefit.  Patent  protection  must  ultimately  be  sought  on  a  country-by-country  basis,  which  is  an
expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we
will not have the benefit of patent protection in such countries.

Moreover, proceedings to enforce our patent rights, or those of our licensors or partners, in foreign jurisdictions could result in substantial costs
and divert our efforts and attention from other aspects of our business, could put our in-licensed patents, or any patents that we may own in the future, at
risk  of  being  invalidated  or  interpreted  narrowly,  could  put  our  owned  or  in-licensed  patent  applications  at  risk  of  not  issuing  and  could  provoke  third
parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be
commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant
commercial advantage from the intellectual property that we develop or license.

If we fail to obtain or maintain patent protection or trade secret protection for our product candidates or our technologies, third parties could use
our  proprietary  information,  which  could  impair  our  ability  to  compete  in  the  market  and  adversely  affect  our  ability  to  generate  revenues  and  attain
profitability.

We may also rely on the trademarks we may develop to distinguish our products from the products of our competitors. We cannot guarantee that
any trademark applications filed by us or our business partners will be approved. Third parties may also oppose such trademark applications, or otherwise
challenge our use of the trademarks. In the event that the trademarks we use are successfully challenged, we could be forced to rebrand our products, which
could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot provide
assurance that competitors will not infringe the trademarks we use, or that we will have adequate resources to enforce these trademarks.

Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our ability
to protect our products.

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and
enforcing patents in the biotechnology industry involve both technological and legal complexity, and it therefore is costly, time-consuming and inherently
uncertain.  In  addition,  on  September  16,  2011,  the  Leahy-Smith  America  Invents  Act  (“AIA”),  was  signed  into  law.  The  AIA  includes  a  number  of
significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation.

An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding
which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that
files a patent application in the U.S. PTO after that date but before us could therefore be awarded a patent covering an invention of ours even if we had
made the invention before it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent
application.

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and providing
opportunities for third parties to challenge any issued patent in the U.S. PTO. This applies to all of our U.S. patents, even those issued before March 16,
2013. Because of a lower evidentiary standard necessary to invalidate a patent claim in the U.S. PTO proceedings compared to the evidentiary standard in
U.S.  federal  court,  a  third  party  could  potentially  provide  evidence  in  a  U.S.  PTO  proceeding  sufficient  for  the  U.S.  PTO  to  hold  a  claim  invalid  even
though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to
use the U.S. PTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a
district court action.

Depending  on  decisions  by  the  U.S.  Congress,  the  federal  courts,  the  U.S.  PTO,  or  similar  authorities  in  foreign  jurisdictions,  the  laws  and
regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing in-licensed
patents and patents that we might obtain in the future.

Our product candidates may infringe the intellectual property rights of others, which could increase our costs and delay or prevent our development
and commercialization efforts.

Our  success  depends  in  part  on  avoiding  infringement  of  the  proprietary  technologies  of  others.  The  pharmaceutical  industry  has  been
characterized by frequent litigation regarding patent and other intellectual property rights. Identification of third-party patent rights that may be relevant to
our proprietary technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the
difficulty in assessing the meaning of patent claims. Additionally, because patent applications are maintained in secrecy until the application is published,
we may be unaware of third-party patents that may be infringed by commercialization of any of our product candidates or any future product candidate.
There may be certain issued patents and patent applications claiming subject matter that we may be required to license in order to research, develop or
commercialize any of our product candidates, and we do not know if such patents and patent applications would be available to license on commercially
reasonable terms, or at all. Any claims of patent infringement asserted by third parties would be time-consuming and may:

● result in costly litigation;

● divert the time and attention of our technical personnel and management;

● prevent us from commercializing a product until the asserted patent expires or is held finally invalid or not infringed in a court of law;

● require us to cease or modify our use of the technology and/or develop non-infringing technology; or

● require us to enter into royalty or licensing agreements.

Third parties may hold proprietary rights that could prevent any of our product candidates from being marketed. Any patent-related legal action
against  us  claiming  damages  and  seeking  to  enjoin  commercial  activities  relating  to  any  of  our  product  candidates  or  our  processes  could  subject  us  to
potential liability for damages and require us to obtain a license to continue to manufacture or market any of our product candidates or any future product
candidates.  We  cannot  predict  whether  we  would  prevail  in  any  such  actions  or  that  any  license  required  under  any  of  these  patents  would  be  made
available on commercially acceptable terms, if at all. In addition, we cannot be sure that we could redesign our product candidates or any future product
candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure
to obtain necessary licenses, could prevent us from developing and commercializing any of our product candidates or a future product candidate, which
could harm our business, financial condition and operating results.

We expect that there are other companies, including major pharmaceutical companies, working in the areas competitive to our proposed product
candidates which either has resulted, or may result, in the filing of patent applications that may be deemed related to our activities. If we were to challenge
the validity of these or any issued U.S. patent in court, we would need to overcome a statutory presumption of validity that attaches to every issued U.S.
patent. This means that, in order to prevail, we would have to present clear and convincing evidence as to the invalidity of the patent’s claims. If we were to
challenge the validity of these or any issued U.S. patent in an administrative trial before the Patent Trial and Appeal Board in the U.S. PTO, we would have
to prove that the claims are unpatentable by a preponderance of the evidence. There is no assurance that a jury and/or court would find in our favor on
questions of infringement, validity or enforceability.

Others may claim an ownership interest in our intellectual property, which could expose us to litigation and have an adverse effect on our prospects.

A third party may claim an ownership interest in one or more of our or our licensors’ patents or other proprietary or intellectual property rights. A
third  party  could  bring  legal  actions  against  us  and  seek  monetary  damages  and/or  enjoin  clinical  testing,  manufacturing  and  marketing  of  the  affected
product or products. We cannot guarantee that a third party will not assert a claim or an interest in any of such patents or intellectual property. If we become
involved  in  any  litigation,  it  could  consume  a  substantial  portion  of  our  resources,  and  cause  a  significant  diversion  of  effort  by  our  technical  and
management personnel. If any of these actions are successful, in addition to any potential liability for damages, we could be required to obtain a license to
continue to manufacture or market the affected product, in which case we may be required to pay substantial royalties or grant cross-licenses to our patents.
We  cannot,  however,  assure  you  that  any  such  license  will  be  available  on  acceptable  terms,  if  at  all.  Ultimately,  we  could  be  prevented  from
commercializing a product candidate, or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation
of other intellectual property rights. Further, the outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in
advance, including the demeanor and credibility of witnesses and the identity of any adverse party. This is especially true in intellectual property cases that
may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree.

We  may  be  subject  to  claims  that  we  have  wrongfully  hired  an  employee  from  a  competitor  or  that  we  or  our  employees  have  wrongfully  used  or
disclosed alleged confidential information or trade secrets of their former employers.

As is commonplace in our industry, we will employ individuals who were previously employed at other pharmaceutical companies, including our
competitors or potential competitors. Although no claims against us are currently pending, we may be subject in the future to claims that our employees or
prospective employees are subject to a continuing obligation to their former employers (such as non-competition or non-solicitation obligations) or claims
that  our  employees  or  we  have  inadvertently  or  otherwise  used  or  disclosed  trade  secrets  or  other  proprietary  information  of  their  former  employers.
Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial
costs and be a distraction to management.

Risks Related to Owning Our Common Stock

An active, liquid and orderly trading market for our shares may not continue to be developed or sustained.

Our common stock is listed on the Nasdaq Global Market. However, trading volume has been limited and a more active public market for our
common stock may not develop or be sustained over time. The market price of our common stock could be subject to significant fluctuations. The price of
our  stock  may  change  in  response  to  variations  in  our  operating  results  and  also  may  change  in  response  to  other  factors,  including  factors  specific  to
companies in our industry many of which are beyond our control. Our shares may be less liquid than the shares of other public companies and there may be
imbalances between supply and demand for our shares. As a result, our share price may experience significant volatility and may not necessarily reflect the
value  of  our  expected  performance.  Moreover,  sales  of  our  common  stock  in  the  public  market,  or  the  perception  that  such  sales  could  occur,  could
negatively  impact  the  price  of  our  common  stock.  As  a  result,  you  may  not  be  able  to  sell  your  shares  of  our  common  stock  in  short  time  periods,  or
possibly at all, and the price per share of our common stock may fluctuate significantly.

Future capital raises may dilute our existing stockholders’ ownership, could depress the market price for our common stock and have other adverse
effects on our operations.

We filed a Form S-3 registration statement (“Shelf Registration”) with the SEC that became effective in December 2019 which will allow us to
sell any combination of common stock, preferred stock, debt securities, warrants to purchase any of these securities, subscription rights to purchase any of
these securities, and/or units consisting of one or more of the foregoing in one or more offerings up to a total dollar amount of $100 million (including the
$22.5 million raised in our October 2020 offering). The issuance of additional shares of our common stock pursuant to the Shelf Registration, or issuances
of securities convertible into or exercisable for our common stock or other equity-linked securities, including preferred stock, warrants, debt securities or
units, would dilute the ownership interest of our common shareholders and could depress the market price of our common stock and impair our ability to
raise capital through the sale of additional equity securities. If we raise additional funds by issuing debt securities, these debt securities would have rights
senior to those of our common stock and the terms of the debt securities issued could impose significant restrictions on our operations, including liens on
our assets. If we raise additional funds through collaborations and licensing arrangements, we may be required to relinquish some rights to our technologies
or candidate products, or to grant licenses on terms that are not favorable to us.

39

 
 
 
 
 
 
 
The trading price of the shares of our common stock may continue to be volatile, and purchasers of our common stock could incur substantial losses.

The trading price of our common stock has fluctuated significantly in the past and is likely to be volatile. The stock market in general, and early
stage  public  companies  in  particular,  has  experienced  extreme  price  and  volume  fluctuations  that  have  often  been  unrelated  or  disproportionate  to  the
operating performance of such companies. The stock market in general has been, and the market price of our shares in particular will likely be, subject to
fluctuation, whether due to, or irrespective of, our operating results and financial condition. The market price of our shares on the Nasdaq Global Market
may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:

● actual or anticipated variations in our and our competitors’ results of operations and financial condition;

● market acceptance of our products;

● the mix of products that we sell and related services that we provide;

● changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;

● development of technological innovations or new competitive products by others;

● announcements of technological innovations or new products by us;

● publication of the results of preclinical or clinical trials for our other product candidates;

● failure by us to achieve a publicly announced milestone;

● delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;

● developments concerning intellectual property rights, including our involvement in litigation brought by or against us;

● regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;

● changes in the structure of healthcare payment systems;

● changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses;

● changes in our expenditures to promote our products;

● our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;

● changes in key personnel;

● success or failure of our research and development projects or those of our competitors;

● the trading volume of our shares; and

● general economic and market conditions and other factors, including factors unrelated to our operating performance.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial
losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class
action  litigation.  If  we  were  involved  in  securities  litigation,  it  could  impose  a  substantial  cost  upon  us  and  divert  the  resources  and  attention  of  our
management from our business.

We are an “emerging growth company” under the JOBS Act of 2012 and we cannot be certain if the reduced disclosure requirements applicable to
emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), and we may take advantage
of  certain  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  “emerging  growth  companies”
including, but not limited to:

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley

Act”);

● reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements;

● exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden

parachute payments; and

● extended transition periods available for complying with new or revised accounting standards.

We have chosen to “opt out” of the extended transition periods available for complying with new or revised accounting standards, but we intend to
take advantage of all of the other benefits available under the JOBS Act, including the exemptions discussed above. We cannot predict if investors will find
our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may
be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an “emerging growth company” for up to five years from the end of the fiscal year following the fifth anniversary of the date of
the first sale of our common stock pursuant to an effective registration statement filed under the Securities Act, which will be December 31, 2023. We will
lose that status sooner, however, if our revenues exceed $1.07 billion, if we issue more than $1 billion in non-convertible debt in a three-year period or if
the market value of our common stock that is held by non-affiliates exceeds $700 million as of any June 30.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or
prevent  fraud.  As  a  result,  stockholders  could  lose  confidence  in  our  financial  and  other  public  reporting,  which  would  harm  our  business  and  the
trading price of our common shares.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure
controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the
Sarbanes-Oxley Act, or the subsequent testing by our independent registered public accounting firm when required, may reveal deficiencies in our internal
controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retrospective changes to our consolidated
financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in
our reported financial information, which could have a negative effect on the trading price of our common shares. There is also a risk that neither we nor
our independent registered public accounting firm (when applicable in the future) will be able to conclude within the prescribed timeframe that internal
controls over financial reporting is effective as required by Section 404. This could result in an adverse reaction in the financial markets due to a loss of
confidence in the reliability of our financial statements.

Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we need it.

Because of the exemptions from various reporting requirements provided to us as an “emerging growth company,” we may be less attractive to
investors and it may be difficult for us to raise additional capital as and when we need it. Investors may be unable to compare our business with other
companies in our industry if they believe that our reporting is not as transparent as other companies in our industry. If we are unable to raise additional
capital as and when we need it, our financial condition and results of operations may be materially and adversely affected.

We have not paid dividends in the past and have no immediate plans to pay dividends, so any returns will be limited to the value of our stock.

We plan to reinvest all of our earnings, to the extent we have earnings, to cover operating costs and otherwise become and remain competitive. We
do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any time, generate
sufficient  surplus  cash  that  would  be  available  for  distribution  to  the  holders  of  our  common  stock  as  a  dividend.  Therefore,  you  should  not  expect  to
receive cash dividends on our common stock, and any return to stockholders will therefore be limited to the appreciation of their stock.

If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our shares, the
price of our shares could decline.

The trading market for our shares will rely in part on the research and reports that equity research analysts publish about us and our business, if at
all. We do not have control over these analysts, and we do not have commitments from them to write research reports about us. The price of our shares
could decline if no research reports are published about us or our business, or if one or more equity research analysts downgrades our shares or if those
analysts issue other unfavorable commentary or cease publishing reports about us or our business.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Our federal net operating losses (NOLs) generated in taxable years ending prior to 2018 could expire unused. Under the Tax Act, federal NOLs
incurred in taxable years ending after December 31, 2017, may be carried forward indefinitely, but the deductibility of federal NOLs generated in tax years
beginning before December 31, 2017, is limited. It is uncertain if and to what extent various states will conform to the Tax Act. In addition, under Sections
382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended,  and  corresponding  provisions  of  state  law,  if  a  corporation  undergoes  an  “ownership
change,” which is generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to
use its pre-change NOL carryforwards, or NOLs, and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be
limited. We are performing a study to determine if we have triggered any “ownership change” limitations. We may also experience ownership changes in
the future as a result of subsequent shifts in our stock ownership some of which may be outside of our control. As a result, if we earn net taxable income,
our ability to use our pre-ownership change NOL carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially
result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise
limited, which could accelerate or permanently increase state taxes owed.

Assuming a market for our common stock continues to develop, sales of a substantial number of shares of our common stock in the public market by
our existing stockholders could cause our stock price to fall.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market or the perception that these sales
might  occur,  could  depress  the  market  price  of  our  common  stock  and  could  impair  our  ability  to  raise  capital  through  the  sale  of  additional  equity
securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.

As of March 8, 2021, we had 24,407,616 shares of common stock outstanding, all of which, other than shares held by our directors and certain
officers, are eligible for sale in the public market, subject in some cases to compliance with the requirements of Rule 144, including volume limitations and
manner of sale requirements.

Certain holders of our securities are entitled to rights with respect to the registration of their shares under the Securities Act of 1933, as amended
(the “Securities Act”). Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the
Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.

We may be at an increased risk of securities class action litigation.

Historically, securities class action litigation has often been brought against a company following a decline in the market price of its securities.
This risk is especially relevant for us because biotechnology and pharmaceutical companies have experienced significant stock price volatility in recent
years. If we were to be sued, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws and applicable provisions of Delaware law
may  delay  or  discourage  transactions  involving  an  actual  or  potential  change  in  control  or  change  in  our  management,  including  transactions  in  which
stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests.
The provisions in our amended and restated certificate of incorporation and amended and restated bylaws:

● authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights

and preferences determined by our board of directors that may be senior to our common stock;

● establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of

persons for election to our board of directors;

● establish that our board of directors is divided into three classes, with each class serving three-year staggered terms;

● require the approval of our board of directors or the holders of at least seventy-five percent (75%) of our outstanding shares of capital stock to

amend our bylaws and certain provisions of our certificate of incorporation;

● limit who may call stockholder meetings;

● do not provide for cumulative voting rights; and

● provide that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

In addition, Section 203 of the Delaware General Corporation Law may limit our ability to engage in any business combination with a person who
beneficially  owns  15%  or  more  of  our  outstanding  voting  stock  unless  certain  conditions  are  satisfied.  This  restriction  lasts  for  a  period  of  three  years
following  the  share  acquisition.  These  provisions  may  have  the  effect  of  entrenching  our  management  team  and  may  deprive  our  stockholders  of  the
opportunity to sell their shares to potential acquirers at a premium over prevailing prices. This potential inability to obtain a control premium could reduce
the price of our common stock.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for
certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes
with us or our directors, officers or stockholders.

Provisions in our amended and restated certificate of incorporation provide that the Court of Chancery of the State of Delaware will, to the fullest

extent permitted by law, be the sole and exclusive forum for:

● any derivative action or proceeding brought on our behalf;

● any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers or other employees;

● any action asserting a claim against us or any of our directors, officers or other employees arising pursuant to any provision of Delaware law

or our charter documents; or

● any action  asserting  a  claim  against  us  or  any  of  our  directors,  officers  or  other  employees  governed  by  the  internal  affairs  doctrine,  but
excluding actions to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive
jurisdiction.

In  addition,  unless  we  consent  in  writing  to  the  selection  of  an  alternative  forum,  the  Federal  district  courts  of  the  United  States  shall  be  the
exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. However, a court may determine that this
provision is unenforceable.

Ownership portions held by our executives and directors, as well as by our former parent company, Harrow Health, Inc., may limit our stockholders’
ability to influence corporate matters.

Our directors and executive officers beneficially own approximately 12.9% of our common stock. Additionally, Harrow Health, Inc. (“Harrow”),
our former parent company, holds approximately 14.3% of our outstanding common stock as of March 8, 2021. Accordingly, these parties, together, can
significantly influence, though not independently determine, the outcome of matters required to be submitted to our stockholders for approval, including
decisions relating to the election of our board of directors and the outcome of any proposed merger or consolidation of our company. These interests may
not be consistent with those of our other stockholders. In addition, the significant interest held by these parties, and particularly by Harrow, may discourage
third parties from seeking to acquire control of us, which may adversely affect the market price of our shares.

As  stockholders  in  our  company,  you  will  be  deemed  to  have  notice  of  and  have  consented  to  the  provisions  of  our  amended  and  restated
certificate of incorporation related to choice of forum, but will not be deemed to have waived our compliance with the federal securities laws and the rules
and regulations thereunder. The choice of forum provisions in our amended and restated certificate of incorporation may limit our stockholders’ ability to
obtain a favorable judicial forum for disputes with us or any of our directors, officers or other employees, which may discourage lawsuits with respect to
such claims. Alternatively, if a court were to find the choice of forum provision contained in our restated charter to be inapplicable or unenforceable in an
action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations and
financial condition.

Overview

We are a unique pharmaceutical company focused on developing, acquiring, and commercializing innovative pharmaceutical products that fulfill an unmet
patient need. Since the formation of our company in 2017, we have used our expertise in business development, regulatory, and product development to
assemble  a  diversified  portfolio  of  nine  products.  All  nine  products  have  now  been  submitted  to  the  FDA  and  three  of  them  have  been  approved  and
commercially launched. We plan to continue growing our business through the acquisition of additional late-stage, high-value product candidates.

Results of Operations

To date we have realized limited revenues from a licensing arrangement on our EM-100 product that was sold to Bausch Health and the launch of
our  Biorphen®  and  Alkindi  Sprinkle®  products  in  December  2019  and  December  2020,  respectively.  We  anticipate  successfully  growing  our  sales  for
these products and commercializing additional product candidates in 2021 and beyond.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019

Net revenues for 2020 reflected limited benefit from Alkindi Sprinkle which launched in December. In addition, revenue was negatively impacted
by a price discount for Biorphen related to the shelf stock at our wholesale customers. Our gross profit was also adversely impacted by a reserve charge to
cost of sales for certain slow-moving Biorphen inventory that we do not believe we will be able to sell before its expiry date. Revenue and gross profit in
2019  reflected  the  initial  launch  for  Biorphen  and  a  $0.5  million  milestone  payment  for  our  sale  of  EM-100  to  Bausch  Health.  For  the  years  ended
December  31,  2020  and  2019,  we  incurred  $14.1  million  and  $11.6  million  of  research  and  development  (“R&D”)  expenses,  respectively,  and  $12.8
million and $7.6 million of general and administrative (“G&A”) expenses, respectively. The comparative period detail of our R&D expense is listed in the
table below. The $5.2 million increase in G&A expenses was primarily due to personnel additions and increased sales/marketing spending to support our
recent product launches. In addition, we incurred significant legal expenses associated with our patent challenge against Exela Pharma Sciences for the
Cysteine product that we have in development. We incurred a net loss of $28.0 million and $18.3 million for the years ended December 31, 2020 and 2019,
respectively.

General and Administrative Expenses

G&A  expenses  consist  primarily  of  employee  compensation  expenses,  selling  and  adverting/promotional  expenses,  legal  and  professional  fees,
business insurance and travel expenses. We anticipate that our G&A expenses will increase to support our business growth – particularly with respect to
sales and marketing for additional personnel and promotional expenses.

Research and Development Expenses

Set  forth  below  is  our  R&D  spending  for  our  current  product  candidates.  We  currently  have  six  employees  that  support  our  overall  product
development and we also have facility and operating costs for a laboratory to support product development. We do not track internal costs by product for
our employees and laboratory expenses and they are listed as indirect expenses in the table below (amounts are in thousands).

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018

For the years ended December 31, 2019 and 2018, we generated $1.0 million and $0 in revenue, respectively. The revenue realized in 2019 was
from a licensing arrangement for our EM-100 product which is pending additional FDA review and the launch of our Biorphen product in December 2019.
For the years 2019 and 2018, we incurred $11.6 million and $5.6 million of research and development (“R&D”) expenses, respectively, and $7.6 million
and $4.7 million of general and administrative (“G&A”) expenses, respectively. The comparative period detail of our R&D expense is listed in the table
below. The $2.9 million increase in G&A expenses was primarily due to additional expenses related to becoming a public company, sales and marketing for
the launch of our Biorphen product, and the impact of personnel additions in the second half of 2018 and first half of 2019. This was partially offset by
lower stock-based consulting expenses. In addition, the change in the fair value of our warrant liability reflected in other expense decreased by $2.6 million
as this mark–to–market accounting treatment was terminated in conjunction with our November 2018 initial public offering (the “IPO”). We incurred a net
loss of $18.3 million and $12.7 million for the years ended December 31, 2019 and 2018, respectively.

Research and Development Expenses

Set  forth  below  is  our  R&D  spending  for  our  product  candidates.  As  of  December  31,  2019,  we  have  ten  employees  that  support  our  overall
product development and we also have facility and operating costs for a laboratory that supports our product development. The laboratory personnel and
related capital equipment additions were added in late 2018. We do not track internal costs by product for our employees and laboratory expenses and they
are listed as indirect expenses in the table below (amounts are in thousands).

Liquidity and Capital Resources

As of December 31, 2020, we had total assets of $26.3 million, cash and cash equivalents of $21.3 million and working capital of $20.9 million.
We  had  previously  capitalized  our  operations  from  the  June  2017  private  placement  of  approximately  $20.1  million  of  Series  A  preferred  stock  which
converted into shares of our common stock concurrent with our IPO in November 2018 and also the IPO which provided us with net proceeds of $22.0
million. In addition, we entered into a Credit Agreement with SWK Holdings in November 2019 whereby we drew a $5.0 million loan amount at closing
and an additional $2.0 million in August 2020. In March and April 2020, we received net proceeds of approximately $7.8 million from the sale of shares of
its  common  stock,  and  in  October  2020,  the  Company  received  net  proceeds  of  approximately  $21.0  million  from  a  public  offering  for  its  shares  at  an
offering price of $7.00 per share. We believe that our existing funding, revenues from our approved products and $9.5 million received in February 2021
from the sale of three pediatric neurology product candidates will be sufficient for at least the next twelve months of our operations. However, our projected
estimates for our product development spending, administrative expenses and our working capital requirements could be inaccurate, or we may experience
growth more quickly or on a larger scale than we expect, any of which could result in the depletion of capital resources more rapidly than anticipated and
could require us to seek additional financing earlier than we expect to support our operations.

Cash Flows

The following table sets forth a summary of our cash flows for the years ended December 31, 2020, 2019 and 2018 (amounts are in thousands):

$

The increase in cash used in operating activities is primarily a result of higher operating losses due to our business expansion including additional
personnel  and  increased  product  candidate  development  activity.  Investing  activities  consist  primarily  of  licensing  fees  for  Biorphen  and  capital
expenditures for setting up our laboratory facility and our headquarters office. The financing activity primarily consists of the November 2018 IPO, the
November 2019 Credit Agreement borrowing from SWK Holdings and the October 2020 follow-on common stock offering.

Critical Accounting Policies

Our financial statements are prepared in accordance with GAAP. The preparation of our financial statements and related disclosures requires us to
make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses in our financial statements. We base our estimates
on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our
estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 3 to our financial statements included herein, we believe that the

following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We account for contracts with our customers in accordance with Accounting Standards Codification (“ASC”) 606 — Revenue from Contracts with
Customers. ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity
recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to
receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC
606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii)
determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the
entity satisfies a performance obligation.

49

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each
contract  and  determines  those  that  are  performance  obligations  and  assesses  whether  each  promised  good  or  service  is  distinct.  We  then  recognize  as
revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.
Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. We assess
whether these options provide a material right to the customer and, if so, they are considered performance obligations. The exercise of a material right is
accounted for as a contract modification for accounting purposes.

We  recognize  as  revenue  the  amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  each
performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts
received  prior  to  revenue  recognition  will  be  recorded  as  deferred  revenue.  Amounts  expected  to  be  recognized  as  revenue  within  the  twelve  months
following the balance sheet date will be classified as current portion of deferred revenue in our balance sheets. Amounts not expected to be recognized as
revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, we will evaluate whether
the  milestone  conditions  have  been  achieved  and  if  it  is  probable  that  a  significant  revenue  reversal  would  not  occur  before  recognizing  the  associated
revenue. Milestone payments that are not within our control or the licensee’s control, such as regulatory approvals, are generally not considered probable of
being achieved until those approvals are received.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a
customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, we will recognize revenue at the
later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or
partially satisfied. To date, we have not recognized any royalty revenue resulting from any of our licensing arrangements.

Significant Financing Component – In determining the transaction price, we will adjust consideration for the effects of the time value of money if

the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one year.

We sell Biorphen in the U.S. to wholesale pharmaceutical distributors, who then sell the product to hospitals and other end-user customers. Sales
to wholesalers are made pursuant to purchase orders subject to the terms of a master agreement, and delivery of individual shipments of Biorphen represent
performance obligations under each purchase order. We use a third-party logistics (“3PL”) vendor to process and fulfill orders and have concluded it is the
principal  in  the  sales  to  wholesalers  because  it  controls  access  to  the  3PL  vendor  services  rendered  and  directs  the  3PL  vendor  activities.  We  have  no
significant obligations to wholesalers to generate pull-through sales. In addition, we sell our Alkindi Sprinkle product to one pharmacy distributor customer
which provides order fulfillment and inventory storage/distribution services.

Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell
Biorphen at negotiated discounted prices to members of certain group purchasing organizations (“GPOs”) and government programs. In addition, we pay
fees to wholesalers for their distribution services, inventory reporting and chargeback processing. We pay GPOs fees for administrative services and for
access to GPO members and concluded the benefits received in exchange for these fees are not distinct from our sales of Biorphen, and accordingly we
apply these amounts to reduce revenues. Wholesalers also have rights to return unsold product nearing or past the expiration date. Because of the shelf life
of Biorphen and our lengthy return period, there may be a significant period of time between when the product is shipped and when we issue credits on
returned product. For our Alkindi Sprinkle product, we bill at the initial product list prices which are subject to offsets for patient co-pay assistance and
potential state Medicaid reimbursements which are recorded as a reduction of net revenues at the date of sale/shipment.

We estimate the transaction price when we receive each purchase order, taking into account the expected reductions of the selling price initially
billed to the wholesaler arising from all of the above factors. We have developed estimates for future returns and chargebacks of Biorphen and the impact
of the other discounts and fees we pay. Our sales of Alkindi Sprinkle to our distributor are not subject to returns. When estimating these adjustments to the
transaction  price,  we  reduce  it  sufficiently  to  be  able  to  assert  that  it  is  probable  that  there  will  be  no  significant  reversal  of  revenue  when  the  ultimate
adjustment amounts are known.

We recognize revenue from Biorphen product sales and related cost of sales upon product delivery to the wholesaler location. At that time, the
wholesalers take control of the product as they take title, bear the risk of loss of ownership, and have an enforceable obligation to pay us. They also have
the ability to direct sales of product to their customers on terms and at prices they negotiate. Although wholesalers have product return rights, we do not
believe they have a significant incentive to return the product to us. We store our Alkindi Sprinkle inventory at our pharmacy distributor customer location
and sales are recorded when stock is pulled and shipped to fulfill specific patient orders.

50

 
 
 
 
 
 
 
 
 
 
 
Upon  recognition  of  revenue  from  product  sales,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,  prompt
payment  discounts,  state  Medicaid  and  GPO  fees  are  included  in  sales  reserves,  accrued  liabilities  and  net  of  accounts  receivable.  We  monitor  actual
product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from our estimates, we will make adjustments to
these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment.

In  addition,  we  anticipate  we  will  receive  revenues  from  product  licensing  agreements  where  we  have  contracted  for  milestone  payments  and

royalties from products we have developed or for which we have acquired the rights to a product developed by a third party.

Stock-Based Compensation

We  account  for  stock-based  compensation  under  the  provisions  of  Accounting  Standards  Codification  (“ASC”)  –  718  Compensation  –  Stock
Compensation. The guidance under ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant and
record expense over the related service periods, which are generally the vesting period of the equity awards. Compensation expense is recognized over the
period  during  which  services  are  rendered  by  consultants  and  non-employees  until  completed.  At  the  end  of  each  financial  reporting  period  prior  to
completion  of  the  service,  the  fair  value  of  these  awards  is  remeasured  using  the  then-current  fair  value  of  our  common  stock  and  updated  assumption
inputs in the Black-Scholes option-pricing model (“BSM”).

We estimate the fair value of stock-based option awards to our using the BSM. The BSM requires the input of subjective assumptions, including
the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant,
among  other  inputs.  The  risk-free  interest  rate  was  determined  from  the  implied  yields  for  zero-coupon  U.S.  government  issues  with  a  remaining  term
approximating the expected life of the options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options.
The expected term of stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable
companies’ historical volatility along with a limited weighting included for our own volatility subsequent to our IPO, which we believe represents the most
accurate basis for estimating expected future volatility under the current conditions. We account for forfeitures as they occur.

Prior  to  our  initial  public  offering  in  November  2018,  the  fair  value  of  the  shares  of  common  stock  underlying  our  stock-based  awards  was
determined by our board of directors, with input from management. Because there had been no public market for our common stock prior to the IPO, our
board of directors had determined the fair value of the common stock on the grant-date of the stock-based award by considering a number of objective and
subjective  factors,  including  enterprise  valuations  of  our  common  stock  performed  by  an  unrelated  third-party  specialist,  valuations  of  comparable
companies, sales of our convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of our capital stock,
and  general  and  industry-specific  economic  outlook.  Following  our  IPO,  we  use  the  closing  stock  price  on  the  date  of  grant  for  the  fair  value  of  the
common stock.

Research and Development Expenses

R&D expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits and
stock-based  compensation  and  other  costs  to  support  our  R&D  operations.  External  contracted  services  include  product  development  efforts  including
certain product licensor milestone payments, clinical trial activities, manufacturing and control-related activities and regulatory costs. R&D expenses are
charged to operations as incurred. We review and accrue R&D expenses based on services performed and rely upon estimates of those costs applicable to
the  stage  of  completion  of  each  project.  Significant  judgments  and  estimates  are  made  in  determining  the  accrued  balances  at  the  end  of  any  reporting
period. Actual results could differ from our estimates.

Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed
as  R&D  in  the  period  in  which  they  are  incurred.  Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  R&D
activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Off Balance Sheet Transactions

We do not have any off-balance sheet transactions.

JOBS Act Transition Period

In April 2012, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), was enacted. Section 107 of the JOBS Act provides that an
“emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with
new  or  revised  accounting  standards.  Thus,  an  emerging  growth  company  can  delay  the  adoption  of  certain  accounting  standards  until  those  standards
would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will
adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

Subject  to  certain  conditions,  as  an  emerging  growth  company,  we  may  rely  on  certain  of  these  exemptions,  including  without  limitation,  (i)
providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act
and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation
or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and
analysis. We will remain an emerging growth company until the earlier to occur of (1) the last day of the fiscal year (a) December 31, 2023, which is the
end of the fiscal year following the fifth anniversary of the completion of our IPO, (b) in which we have total annual gross revenues of at least $1.07 billion
or (c) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means the market value of our common stock that is held
by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt
during the prior three-year period.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The  primary  objective  of  our  investment  activities  is  to  preserve  capital.  We  do  not  utilize  hedging  contracts  or  similar  instruments.  We  are
exposed to certain market risks relating primarily to interest rate risk on our cash and cash equivalents and risks relating to the financial viability of the
institutions which hold our capital and through which we have invested our funds. We manage such risks by investing in short-term, liquid, highly rated
instruments.  As  of  December  31,  2020,  our  cash  equivalents  are  invested  primarily  in  short-term  U.S.  treasury  bills.  We  do  not  believe  we  have  any
material exposure to interest rate risk due to the extremely low interest rate environment and the short duration of the invested funds we hold. Declines in
interest  rates  would  reduce  our  investment  income  but  would  not  have  a  material  effect  on  our  financial  condition  or  results  of  operations.  We  do  not
currently have exposure to foreign currency risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Eton Pharmaceuticals, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Eton  Pharmaceuticals,  Inc.  (the  “Company”)  as  of  December  31,  2020  and  2019,  the  related
statements of operations, redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the three years in the period
ended  December  31,  2020,  and  the  related  notes  and  the  financial  statement  schedule  listed  in  the  Index  at  Item  15(2)  (collectively  referred  to  as  the
“financial  statements”).  In  our  opinion,  the  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of
December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in
conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements
based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of
internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over
financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2)
involved  our  especially  challenging,  subjective,  or  complex  judgments.  The  communication  of  the  critical  audit  matter  does  not  alter  in  any  way  our
opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the
critical audit matter or on the accounts or disclosures to which it relates.

Product Sales Deductions

Critical Audit Matter Description

As described in Note 3 to the financial statements under the caption “Revenue Recognition for Contracts with Customers,” revenues from product sales are
recognized net of reductions for estimated returns, chargebacks, distribution fees, prompt payment discounts, state Medicaid and GPO fees (collectively
“sales deductions”), which are established at the time of sale.

Auditing the estimation of sales deductions was challenging because of the limited sales history of the Company’s products and the subjectivity of certain
assumptions  required  to  estimate  those  amounts.  In  particular,  management  estimates  potential  chargebacks,  which  relate  to  price  reductions  below  the
estimated sales price that the wholesalers provide to certain customers, based on historical industry data for competitive products and adjusted for actual
historical  experience.  In  addition,  management  estimates  its  provision  for  product  returns  based  on  prior  experience  with  similar  product  launches  and
considers other factors such as levels of inventory in the distribution channel, forecasted buying patterns, and product dating and expiration period. The
product  sales  deductions  are  estimated  based  on  current  contractual  and  statutory  requirements,  market  events  and  trends,  and  internal  and  external
historical data.

How the Critical Audit Matter Was Addressed in the Audit

To test management’s estimated product sales deductions, we obtained management’s calculations for the respective estimates and performed the following
procedures, among others. We tested management’s estimation process for determining of product sales discounts accruals by developing an independent
expectation of the estimated accrual rate, including a comparison of rates used in management’s forecast to rates in the underlying contracts and performing
a retrospective review of assumptions to actual activity. In addition, we assessed subsequent events to determine whether there was any new information
that would require adjustment to the initial accruals, evaluated trends in actual sales and discount accrual balances, compared cash receipts to product sales.
We  also  reviewed  terms  and  conditions  for  a  sample  of  contracts  with  the  Company’s  customers,  tested  a  sample  of  credits  issued  and  payments  made
throughout the year and agreed rates to underlying contract terms.

Eton Pharmaceuticals, Inc.
NOTES TO FINANCIAL STATEMENTS
(in thousands, except share and per share amounts)

Note 1 — Company Overview

Eton Pharmaceuticals, Inc. (“Eton” or the “Company”) was incorporated as a Delaware “C” corporation on April 27, 2017 and was initially set up
as a wholly-owned subsidiary of Harrow Health, Inc. (“Harrow”, fka Imprimis Pharmaceuticals, Inc.). In June 2017, the Company raised $20,055 in start-
up capital through a private sale of preferred stock and a separate management team was then established for Eton with its corporate offices located in Deer
Park,  Illinois.  In  November  2018,  the  Company  completed  an  initial  public  offering  (the  “IPO”)  and  received  net  proceeds  of  $21,960,  after  deducting
underwriting discounts and commissions and offering-related expenses. In November 2019, the Company entered into a credit agreement and received net
proceeds of $4,750 and in August 2020 the Company received net proceeds of $1,965 under the credit agreement (see Note 5). In March and April 2020,
Eton received net proceeds of $7,756 from the sale of shares of its common stock and in October 2020, the Company received net proceeds of $21,026
from a public offering for its shares at an offering price of $7.00 per share (see Note 7).

Eton  is  a  specialty  pharmaceutical  company  focused  on  developing,  acquiring,  and  commercializing  innovative  products.  Eton  is  primarily
focused  on  hospital  injectable  and  pediatric  rare  disease  products.  The  Company  seeks  to  improve  the  formula,  delivery  system,  or  safety  of  existing
molecules in order to address unmet patient needs. Eton pursues what it perceives to be low-risk product candidates where existing published literature,
historical clinical trials, or physician usage has established safety and/or efficacy of the molecule, thereby reducing the incremental clinical burden required
for the Company to bring the product to patients.

The Company’s Biorphen® product was approved by the FDA in October 2019 and sales commenced for this product at the end of 2019. Eton’s
EM-100 product was sold to Bausch Health and the product was approved by the FDA in September 2020. Bausch Health launched this product under the
name of Alaway® Preservative Free in January 2021 and Eton will receive royalties from the sale of the product. In addition, the Company acquired the
licensing rights to Alkindi Sprinkle and this product was approved by the FDA in October 2020 and launched in December 2020.

Note 2 — Liquidity Considerations

As of December 31, 2020, the Company had an accumulated deficit of $92,158 and for the year ended December 31, 2020 the Company used net

cash in operating activities of $22,346.

To  date,  the  Company  has  generated  limited  revenues  from  three  products,  but  expects  further  growth  in  2021  and  beyond  in  accordance  with
additional market penetration from these products plus revenues from licensing and additional products where it anticipates FDA approval. The Company
currently believes its existing cash and cash equivalents of $21,295 as of December 31, 2020 augmented by the $9,500 of proceeds received from the sale
of three neurology products in February 2021 (see Note 16 — Subsequent Events), will be sufficient to fund its operating expenses and capital expenditure
requirements for at least the next twelve months from the date of issuance of these financial statements. This estimate is based on the Company’s current
assumptions, including assumptions relating to estimated sales and its ability to manage its spending. The Company could use its available capital resources
sooner than currently expected. Accordingly, the Company could seek to obtain additional capital through equity financings, the issuance of debt or other
arrangements. However, there can be no assurance that the Company will be able to raise additional capital if needed or under acceptable terms, if at all.
The sale of additional equity may dilute existing stockholders and newly issued shares may contain senior rights and preferences compared to currently
outstanding common shares. The Company’s existing long-term debt obligation contains covenants and limits the Company’s ability to pay dividends or
make other distributions to stockholders. If the Company experiences delays in product sales growth and completing its product development and obtaining
regulatory  approval  for  its  other  product  candidates  and  is  unable  to  obtain  such  additional  financing,  operations  would  need  to  be  scaled  back  or
discontinued.

Note 3 — Summary of Significant Accounting Policies

Basis of Presentation

The  Company  has  prepared  the  accompanying  financial  statements  in  accordance  with  accounting  principles  generally  accepted  in  the  United

States of America (“GAAP”).

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities,  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of
revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited
to, provisions for uncollectible receivables and sales returns, valuation of inventories, useful lives of assets and the impairment of property and equipment,
the accrual of research and development expenses and the valuation of common stock, stock options, warrants and derivative instruments. Estimates are
periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become
known. Actual results could differ from those estimates or assumptions.

Segment Information

The  Company  operates  the  business  on  the  basis  of  a  single  reportable  segment,  which  is  the  business  of  developing  and  commercializing
prescription drug products. The Company’s chief operating decision-maker is the Chief Executive Officer (“CEO”), who evaluates the Company as a single
operating segment.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash
equivalents  are  held  in  U.S.  financial  institutions  or  invested  in  short-term  U.S.  treasury  bills.  Cash  equivalents  consist  of  an  interest-bearing  checking
account and a U.S. treasury bill. From time to time, amounts deposited with its bank exceed federally insured limits. The Company believes the associated
credit risk to be minimal.

Accounts Receivable

Accounts  receivable  are  recorded  at  the  invoiced  amount  and  are  non-interest  bearing.  Accounts  receivable  are  recorded  net  of  allowances  for
doubtful accounts, cash discounts for prompt payment, distribution fees, chargebacks and returns and allowances. The total for these reserves amounted to
$71 and $116 as of December 31, 2020 and 2019, respectively.

Inventories

The  Company  values  its  inventories  at  the  lower  of  cost  or  net  realizable  value  using  the  first-in,  first-out  method  of  valuation. The  Company
reviews its inventories for potential excess or obsolete issues on an ongoing basis and will record a write-down if an impairment is identified. Inventories at
December 31, 2020 and 2019 consist solely of purchased finished goods. At December 31, 2020, inventories are shown net of a slow-moving reserve for its
Biorphen product of $623 due to the risk of expiry before this entire stock of inventories is sold. There was no inventory reserve at December 31, 2019.

Property and Equipment

Property  and  equipment  are  stated  at  cost.  Depreciation  of  property  and  equipment  is  computed  utilizing  the  straight-line  method  based  on  the
following estimated useful lives. Computer hardware and software is depreciated over three years. Equipment, furniture and fixtures is depreciated over
five  years.  Leasehold  improvements  are  amortized  over  their  estimated  useful  lives  or  the  remaining  lease  term,  whichever  is  shorter.  Construction  in
progress is capitalized but not depreciated until it is placed into service.

Maintenance and repairs are charged to expense as incurred, while renewals and improvements are capitalized.

Note 3 — Summary of Significant Accounting Policies (continued)

Intangible Assets

The Company capitalizes payments it makes for licensed products when the payment is based on FDA approval for the product and the cost is
recoverable based on expected future cash flows from the product. The cost is amortized on a straight-line basis over the estimated useful life of the product
commencing  on  the  approval  date  in  accordance  with  Accounting  Standards  Codification  (“ASC”)  350  —  Intangibles  -  Goodwill  and  Other.  A  $750
payment related to the approval of the Company’s Biorphen product in 2019 has been capitalized and that cost is being amortized over five years. The
intangible assets, net on the Company’s balance sheet reflected $175 and $25 of accumulated amortization as of December 31, 2020 and 2019, respectively.
The Company recorded amortization expense of $150 and $25 for the years ended December 31, 2020 and 2019, respectively and will record amortization
expense of $150 per year for this intangible asset for 2021 through 2023 and then $125 in 2024 when it will be fully amortized.

Impairment of Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted
future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is
recognized in the Company’s statements of operations for the amount by which the carrying amount of the asset exceeds the fair value of the asset. No
impairment was recognized during the years ended December 31, 2020, 2019 and 2018.

Debt Issuance Costs and Debt Discount and Detachable Debt-Related Warrants

Costs  incurred  to  issue  debt  are  deferred  and  recorded  as  a  reduction  to  the  debt  balance  in  the  accompanying  balance  sheets.  The  Company
amortizes debt issuance costs over the expected term of the related debt using the effective interest method. Debt discounts relate to the relative fair value
of warrants issued in conjunction with the debt and are also recorded as a reduction to the debt balance and accreted over the expected term of the debt to
interest expense using the effective interest method.

Classification and Accretion of Redeemable Convertible Preferred Stock

Prior to the Company’s IPO in November 2018, the Company classified the Series A Preferred outside of stockholders’ equity (deficit) because
the shares contained certain redemption features that were not solely within the control of the Company. The carrying value of the Series A Preferred was
accreted to its redemption value from the date of issuance through November 15, 2018, the date of the Company’s IPO. In conjunction with the IPO, the
Series A Preferred, including accrued and unpaid dividends, automatically converted to shares of the Company’s common stock (see Note 6).

Beneficial Conversion Feature

Prior to the IPO in November 2018, the Company classified its Series A Preferred as temporary equity due to a possible cash redemption feature
in the event that an IPO or alternate financing was not completed by December 31, 2018. At the IPO date, the Series A Preferred, and related accrued and
unpaid dividends, automatically converted into shares of the Company’s common stock. The conversion share calculation was based on the $3.00 initial
issuance price for the Series A Preferred plus any accrued but unpaid dividends and converted to common stock using a stated divisor conversion price
equal to 50% of the IPO price to the public, which was $6.00 per share. In accordance with relevant accounting literature, since the stated terms of the
conversion option did not permit the Company to compute the additional number of shares that it would need to issue upon conversion of the Series A
Preferred when the contingent event occurred, the Company recorded the beneficial conversion amount of $21,747 as a deemed dividend at the date of the
IPO in November 2018.

Note 3 — Summary of Significant Accounting Policies (continued)

Leases

The Company adopted ASC Topic 842 — Leases, effective January 1, 2019, using the modified retrospective method. The reported results for
fiscal years 2020 and 2019 reflect the application of ASC Topic 842, while the reported results for the year ended December 31, 2018 are not adjusted and
continue to be reported under the prior ASC Topic 840 guidance for leases.

The Company reviews all relevant facts and circumstances of a contract to determine if it is a lease whereby the terms of the agreement convey the
right to control the direct use and receive substantially all of the economic benefits of an identified asset for a period of time in exchange for consideration.
The associated right-of-use assets and lease liabilities are recognized at lease commencement. The Company measures lease liabilities based on the present
value of the lease payments over the lease term discounted using the rate it would pay on a loan with the equivalent payments and term for the lease. The
Company does not include the impact for lease term options that would extend or terminate the lease unless it is reasonably certain that it will exercise any
such options. The Company accounts for the lease components separately from non-lease components for its operating leases.

The Company measures right-of-use assets based on the corresponding lease liabilities adjusted for (i) any prepayments made to the lessor at or
before  the  commencement  date,  (ii)  initial  direct  costs  it  incurs,  and  (iii)  any  incentives  under  the  lease.  In  addition,  the  Company  evaluates  the
recoverability of its right-of-use assets for possible impairment in accordance with its long-lived assets policy.

Operating leases are reflected on the balance sheets as operating lease right-of-use assets, current accrued liabilities and long-term operating lease

liabilities. The Company does not have any finance leases as of December 31, 2020 and 2019.

The Company commences recognizing operating lease expense when the lessor makes the underlying asset available for use by the Company and

the operating lease expense is recognized on a straight-line basis. Variable lease payments are expensed as incurred.

The  Company  does  not  recognize  right-of-use  assets  or  lease  liabilities  for  leases  with  a  term  of  twelve  months  or  less;  such  lease  costs  are

recorded in the statements of operations on a straight-line basis over the lease term.

Patent Costs

All  patent-related  costs  incurred  in  connection  with  filing  and  prosecuting  patent  applications  are  expensed  as  incurred  due  to  the  uncertainty

about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

Concentrations of Credit Risk, Sources of Supply and Significant Customers

The Company is subject to credit risk for its cash and cash equivalents which are invested in money market funds and a U.S. treasury bill. The
Company maintains its cash and cash equivalent balances with one major commercial bank and the deposits held with the financial institution exceed the
amount of insurance provided on such deposits and is exposed to credit risk in the event of a default by the financial institutions holding its cash and cash
equivalents to the extent recorded on the balance sheets.

The  Company  is  dependent  on  third-party  suppliers  for  its  products  and  product  candidates.  In  particular,  the  Company  relies,  and  expects  to
continue  to  rely,  on  a  small  number  of  suppliers  to  manufacture  key  chemicals,  approved  products  and  process  its  product  candidates  as  part  of  its
development programs. These programs could be adversely affected by a significant interruption in the manufacturing process.

Note 3 — Summary of Significant Accounting Policies (continued)

The Company is also subject to credit risk from its accounts receivable related to product sales as it extends credit based on an evaluation of the
customer’s  financial  condition,  and  collateral  is  not  required.  Management  monitors  its  exposure  to  accounts  receivable  by  periodically  evaluating  the
collectability of the account receivable based on a variety of factors including the length of time the receivables are past due, the financial health of the
customer and historical experience. Based upon the review of these factors, the Company recorded no allowance for doubtful accounts at December 31,
2020 or 2019. The accounts receivable balance at December 31, 2020 and 2019 and product sales revenue recognized during the year ended December 31,
2020 and 2019 consist of sales to and amounts due from AmerisourceBergen Corporation, Cardinal Health Services and McKesson Corporation for sales of
the  Company’s  Biorphen  product.  The  December  31,  2020  accounts  receivable  balance  and  sales  in  2020  also  include  sales  to  and  amounts  due  from

Revenue Recognition for Contracts with Customers

The  Company  accounts  for  contracts  with  its  customers  in  accordance  with  ASC  606  —  Revenue  from  Contracts  with  Customers.  ASC  606
applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when
its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for
those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs
the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction
price;  (iv)  allocate  the  transaction  price  to  the  performance  obligations  in  the  contract;  and  (v)  recognize  revenue  when  (or  as)  the  entity  satisfies  a
performance obligation.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised
within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company
then  recognizes  as  revenue  the  amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  the  performance
obligation  is  satisfied.  Arrangements  that  include  rights  to  additional  goods  or  services  that  are  exercisable  at  a  customer’s  discretion  are  generally
considered  options.  The  Company  assesses  whether  these  options  provide  a  material  right  to  the  customer  and,  if  so,  they  are  considered  performance
obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes.

The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as)
each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts
received  prior  to  revenue  recognition  will  be  recorded  as  deferred  revenue.  Amounts  expected  to  be  recognized  as  revenue  within  the  twelve  months
following the balance sheet date will be classified as current portion of deferred revenue in the Company’s balance sheets. Amounts not expected to be
recognized as revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, the Company will evaluate
whether  the  milestone  conditions  have  been  achieved  and  if  it  is  probable  that  a  significant  revenue  reversal  would  not  occur  before  recognizing  the
associated revenue. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are generally not
considered probable of being achieved until those approvals are received.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a
customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, the Company will recognize
revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has
been satisfied or partially satisfied. To date, the Company has not recognized any royalty revenue resulting from any of its licensing arrangements.

Significant Financing Component – In determining the transaction price, the Company will adjust consideration for the effects of the time value of
money if the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one
year.

The  Company  sells  Biorphen  in  the  U.S.  to  wholesale  pharmaceutical  distributors,  who  then  sell  the  product  to  hospitals  and  other  end-user
customers. Sales to wholesalers are made pursuant to purchase orders subject to the terms of a master agreement, and delivery of individual shipments of
Biorphen  represent  performance  obligations  under  each  purchase  order.  The  Company  uses  a  third-party  logistics  (“3PL”)  vendor  to  process  and  fulfill
orders and has concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor services rendered and directs the 3PL
vendor  activities.  The  Company  has  no  significant  obligations  to  wholesalers  to  generate  pull-through  sales.  In  addition,  the  Company  sells  its  Alkindi
Sprinkle product to one pharmacy distributor customer which provides order fulfilment and inventory storage/distribution services.

Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell
Biorphen  at  negotiated  discounted  prices  to  members  of  certain  group  purchasing  organizations  (“GPOs”)  and  government  programs.  In  addition,  the
Company  pays  fees  to  wholesalers  for  their  distribution  services,  inventory  reporting  and  chargeback  processing.  The  Company  pays  GPOs  fees  for
administrative services and for access to GPO members and concluded the benefits received in exchange for these fees are not distinct from its sales of
Biorphen, and accordingly it applies these amounts to reduce revenues. Wholesalers also have rights to return unsold product nearing or past the expiration
date. Because of the shelf life of Biorphen and the Company’s lengthy return period, there may be a significant period of time between when the product is
shipped and when it issues credits on returned product. For its Alkindi Sprinkle product, the Company bills at the initial product list price which are subject
to  offsets  for  patient  co-pay  assistance  and  potential  state  Medicaid  reimbursements  which  are  recorded  as  a  reduction  of  net  revenues  at  the  date  of
sale/shipment.

The Company estimates the transaction price when it receives each purchase order taking into account the expected reductions of the selling price
initially billed to the wholesaler/distributor arising from all of the above factors. The Company has developed estimates for future returns and chargebacks
of Biorphen and the impact of the other discounts and fees it pays while Alkindi Sprinkle sales to its distributor are not subject to returns. When estimating
these adjustments to the transaction price, the Company reduces it sufficiently to be able to assert that it is probable that there will be no significant reversal
of revenue when the ultimate adjustment amounts are known.

The Company recognizes revenue from Biorphen product sales and related cost of sales upon product delivery to the wholesaler location. At that
time,  the  wholesalers  take  control  of  the  product  as  they  take  title,  bear  the  risk  of  loss  of  ownership,  and  have  an  enforceable  obligation  to  pay  the
Company. They also have the ability to direct sales of product to their customers on terms and at prices they negotiate. Although wholesalers have product
return rights, the Company does not believe they have a significant incentive to return the product. The Company stores its Alkindi Sprinkle inventory at its
pharmacy distributor customer location and sales are recorded when stock is pulled and shipped to fulfill specific patient orders.

Upon  recognition  of  revenue  from  product  sales,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,  prompt
payment discounts, state Medicaid and GPO fees are included in sales reserves, accrued liabilities and net of accounts receivable. The Company monitors
actual product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from its estimates, it will make adjustments
to these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment.

In addition, the Company anticipates it will receive revenues from product licensing agreements where it has contracted for milestone payments

and royalties from products it has developed or for which it has acquired the rights to a product developed by a third party.

Note 3 — Summary of Significant Accounting Policies (continued)

Cost of Product Sales

Cost of product sales consists of the profit-sharing and royalty fees with the Company’s product licensing and development partners, the purchase
costs for finished products from third-party manufacturers and freight and handling/storage costs from the Company’s 3PL logistics service providers. The
cost of sales for profit-sharing and royalty fees and costs for purchased finished products and the associated inbound freight expense is recorded when the
associated  product  sale  revenue  is  recognized  in  accordance  with  the  terms  of  shipment  to  customers  while  outbound  freight  and  handling/storage  fees
charged  by  the  3PL  service  provider  are  expensed  as  they  are  incurred.  Cost  of  sales  also  reflects  any  write-downs  or  reserve  adjustments  for  the
Company’s inventories.

Research and Development Expenses

Research  and  development  (“R&D”)  expenses  include  both  internal  R&D  activities  and  external  contracted  services.  Internal  R&D  activity
expenses include salaries, benefits and stock-based compensation and other costs to support the Company’s R&D operations. External contracted services
include  product  development  efforts  such  as  certain  product  licensor  milestone  payments,  clinical  trial  activities,  manufacturing  and  control-related
activities and regulatory costs. R&D expenses are charged to operations as incurred. The Company reviews and accrues R&D expenses based on services
performed and relies upon estimates of those costs applicable to the stage of completion of each project. Significant judgments and estimates are made in
determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates.

Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed
as  R&D  in  the  period  in  which  they  are  incurred.  Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  R&D
activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Earnings (Loss) Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders for the period by the weighted average
number  of  common  shares  outstanding  during  the  period.  Diluted  net  loss  per  share  is  computed  by  dividing  the  net  loss  attributable  to  common
stockholders for the period by the weighted average number of common and common equivalent shares, such as Series A Preferred, unvested restricted
stock,  stock  options  and  warrants  that  are  outstanding  during  the  period.  Common  stock  equivalents  are  excluded  from  the  computation  when  their
inclusion would be anti-dilutive. No such adjustments were made for 2020, 2019 or 2018 as the Company reported a net loss for the years ended December
31, 2020, 2019 and 2018 and including the effects of common stock equivalents in the diluted earnings per share calculation would have been antidilutive
(see Note 10).

Warrant Liability

The Company estimated the fair value of certain warrants at each reporting period using Level 3 inputs. The estimates in valuation models were
based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk-free interest rate and
the  exercise  price  of  the  warrants.  Changes  in  the  fair  value  of  the  warrant  liability  during  the  period  were  recorded  as  a  component  of  other  income
(expense) at the end of each reporting period for changes in fair value until the Company’s IPO in November 2018, which established a fixed number of
shares for these warrants. At the date of the IPO, the warrant liability amount was reclassified as a component of additional paid-in-capital.

Stock-Based Compensation

The Company accounts for stock-based compensation under the provisions of ASC — 718 Compensation — Stock Compensation. The guidance under
ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant and record expense over the related
service periods, which are generally the vesting period of the equity awards. The Company estimates the fair value of stock-based option awards using the
Black-Scholes-Merton option-pricing model (“BSM”). The BSM requires the input of subjective assumptions, including the expected stock price volatility,
the  calculation  of  expected  term,  forfeitures  and  the  fair  value  of  the  underlying  common  stock  on  the  date  of  grant,  among  other  inputs.  The  risk-free
interest rate was determined from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the
options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options
granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies’ historical volatility
along with a limited weighting included for the Company’s own volatility subsequent to its IPO, which management believes represents the most accurate
basis for estimating expected future volatility under the current conditions. The Company accounts for forfeitures as they occur. Since the IPO in November
2018, the Company has used the closing common stock price on the date of grant for the fair value of the common stock.

Note 3 — Summary of Significant Accounting Policies (continued)

Prior to the Company’s IPO, the fair value of the shares of the Company’s common stock underlying its stock-based awards was determined by its
board of directors, with input from management. Because there had been no public market for the Company’s common stock prior to the IPO, the board of
directors  had  determined  the  fair  value  of  the  common  stock  on  the  grant-date  of  the  stock-based  award  by  considering  a  number  of  objective  and
subjective  factors,  including  enterprise  valuations  of  its  common  stock  performed  by  an  unrelated  third-party  specialist,  valuations  of  comparable
companies, sales of its convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of the capital stock,
and general and industry-specific economic outlook. Following the IPO in November 2018, the Company uses the closing stock price on the date of grant
for the fair value of the common stock.

Income Taxes

As part of the process of preparing the Company’s financial statements, the Company must estimate the actual current tax liabilities and assess
temporary  differences  resulting  from  differing  treatment  of  items  for  tax  and  accounting  purposes.  These  differences  result  in  deferred  tax  assets  and
liabilities, which are included within the balance sheets. The Company must assess the likelihood that the deferred tax assets will be recovered from future
taxable income and, to the extent the Company believes that recovery is not likely, a valuation allowance must be established. To the extent the Company
establishes a valuation allowance or increase or decrease to this allowance in a period, the impact will be included in income tax expense in the statements
of operations. As of December 31, 2020 and 2019, the Company has established a 100% valuation reserve against its deferred tax assets.

The Company accounts for income taxes under the provisions of ASC 740 - Income Taxes. As of December 31, 2020 and 2019, there were no
unrecognized tax benefits included in the balance sheets that would, if recognized, affect the effective tax rate. The Company’s practice is to recognize
interest and penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties in its balance sheets at
December 31, 2020 or 2019, and has not recognized interest and penalties in the statements of operations for the years ended December 31, 2020, 2019 and
2018. As of December 31, 2020, the Company is subject to taxation in the United States and certain individual states – primarily Illinois and Tennessee.
The Company’s tax losses from 2017 through 2020 are subject to examination by the federal and state tax authorities due to the carryforward of unutilized
net operating losses (“NOLs”).

The Tax  Cuts  and  Jobs  Act  of  2017  (the  “Tax  Act”)  significantly  revised  U.S.  corporate  income  tax  law  by,  among  other  things,  reducing  the
corporate income tax rate to 21% and implementing a modified territorial tax system. In response to the Tax Act, the SEC issued Staff Accounting Bulletin
(“SAB”) 118 which allows issuers to recognize provisional estimates of the impact of the Tax Act in their financial statements and adjust in the period in
which  the  estimates  become  finalized,  or  in  circumstances  where  estimates  cannot  be  made,  to  disclose  and  recognize  within  a  one-year  measurement
period.

Current  accounting  standards  include  guidance  on  the  accounting  for  uncertainty  in  income  taxes  recognized  in  the  financial  statements.  Such
standards also prescribe a recognition threshold and measurement model for the financial statement recognition of a tax position taken, or expected to be
taken, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company
believes that the ultimate deductibility of all tax positions is highly certain, although there is uncertainty about the timing of such deductibility. As a result,
no liability for uncertain tax positions was recorded as of December 31, 2020 or 2019.

Fair Value Measurements

We  measure  certain  of  our  assets  and  liabilities  at  fair  value.  Fair  value  represents  the  price  that  would  be  received  to  sell  an  asset  or  paid  to
transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date.  Fair  value  accounting  requires  characterization  of  the
inputs used to measure fair value into a three-level fair value hierarchy as follows:

Eton Pharmaceuticals, Inc.
NOTES TO FINANCIAL STATEMENTS
(in thousands, except share and per share amounts)

Note 3 — Summary of Significant Accounting Policies (continued)

Level 1 — Inputs based on quoted prices in active markets for identical assets or liabilities. An active market is a market in which transactions

occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Observable inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market

data obtained from sources independent from the entity.

Level 3 — Unobservable inputs that reflect the entity’s own assumptions about the assumptions market participants would use in pricing the asset

or liability developed based on the best information available.

Fair value measurements are classified based on the lowest level of input that is significant to the measurement. The Company’s assessment of the
significance  of  a  particular  input  to  the  fair  value  measurement  requires  judgment,  which  may  affect  the  valuation  of  the  assets  and  liabilities  and  their
placement  within  the  fair  value  hierarchy  levels.  The  determination  of  the  fair  values  stated  below  takes  into  account  the  market  for  the  Company’s
financials,  assets  and  liabilities,  the  associated  credit  risk  and  other  factors  as  required.  The  Company  considers  active  markets  as  those  in  which
transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

The  Company’s  financial  instruments  included  cash  and  cash  equivalents,  accounts  receivable,  accounts  payable,  accrued  liabilities,  PPP  and
EIDL loans and long-term debt obligation. The carrying amounts of these financial instruments, except for the PPP and EIDL loans and long-term debt
obligation,  approximate  their  fair  values  due  to  the  short-term  maturities  of  these  instruments.  Based  on  borrowing  rates  currently  available  to  the
Company, the carrying value of the PPP and EIDL loans and long-term debt obligation approximate their fair values.

The  fair  values  of  the  Company’s  warrant  liability  at  inception  and  for  subsequent  mark-to-market  fair  value  measurements  were  based  on
management’s valuation model and expectations with respect to the method and timing of settlement. The Company determined that the warrant liability
fair values were classified as Level 3 measurements within the fair value hierarchy. At the date of the Company’s IPO in November 2018, the fair value
was reclassified to additional paid-in-capital as the final number of shares for the warrants previously reflected as a liability became fixed (see Note 6).

Impact of New Accounting Pronouncements

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments  -  Credit  Losses  (Topic  326),  Measurement  of  Credit  Losses  on  Financial
Instruments.  The  standard  amends  the  impairment  model  by  requiring  entities  to  use  a  forward-looking  approach  based  on  expected  losses  to  estimate
credit  losses  for  most  financial  assets  and  certain  other  instruments  that  are  not  measured  at  fair  value  through  net  income.  For  available-for-sale  debt
securities, entities will be required to recognize an allowance for credit losses rather than a reduction in carrying value of the asset. Entities will no longer
be permitted to consider the length of time that fair value has been less than amortized cost when evaluating when credit losses should be recognized. The
Company adopted the new guidance on January 1, 2020 which did not have a material impact on its financial position or results of operations.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820). The new guidance removes, modifies and adds to certain
disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The Company adopted the new guidance on January 1, 2020
which did not have a material impact on its financial position or results of operations.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The new guidance removes certain exceptions
to  the  general  principles  of  ASC  740  in  order  to  simplify  the  complexities  of  its  application.  These  changes  include  eliminations  to  the  exceptions  for
intraperiod tax allocation, recognizing deferred tax liabilities related to outside basis differences, and year-to-date losses in interim periods among others.
The Company adopted ASU 2019-12 in January 2020 and it did not have have a material impact on its financial position or results of operations.

Note 5 – Debt

SWK Loan

On November 13, 2019, the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Holdings Corporation (“SWK”)
which provided for up to $10,000 in financing. The Company received proceeds of $5,000 at closing and was able to borrow an additional $5,000 upon the
FDA approval of a second product developed by the Company, excluding EM-100. In March 2020, in conjunction with the Company’s Alkindi Sprinkle
product licensing agreement (see Note 15) and the Company’s March 2020 sale of additional shares of its common stock (see Note 7), the Company and
SWK amended the SWK Credit Agreement. The amendment provided the Company with the option to immediately draw $2,000 and the ability to borrow
an additional $3,000 based upon the FDA approval of EM-100 and Alkindi Sprinkle which subsequently occurred in September 2020. Accordingly, the
Company borrowed an additional $2,000 on August 11, 2020. The term of the SWK Credit Agreement is for five years and borrowings bear interest at a
rate of LIBOR 3-month plus 10.0%, subject to a stated LIBOR floor rate of 2.0%. A 2.0% unused credit limit fee is assessed during the first twelve months
after the date of the SWK Credit Agreement and loan fees include a 5.0% exit fee based on the principal amounts drawn which is payable at the end of the
term of the SWK Credit Agreement. The Company is required to maintain a minimum cash balance of $3,000, will only pay interest on the debt until May
2022 and then will pay 5.5% of the loan principal balance commencing on February 15, 2022 and then every three months thereafter until November 13,
2024 at which time the remaining principal balance is due. Borrowings under the SWK Credit Agreement are secured by the Company’s assets. The SWK
Credit Agreement contains customary default provisions and covenants which include limits on additional indebtedness. In March 2020, SWK provided a
waiver for the Company to obtain loans with the Small Business Association. The Company is currently in the process of negotiating covenant targets for
EBITDA and revenue for the SWK Credit Agreement. In February 2021, the Company notified SWK that it will not require additional borrowing capacity
under the SWK Credit Agreement and terminated the additional borrowing capacity with SWK.

In  connection  with  the  initial  $5,000  borrowed  in  November  2019,  the  Company  issued  warrants  to  SWK  to  purchase  51,239  shares  of  the
Company’s common stock with an exercise price of $5.86 per share. The relative fair value of these 51,239 warrants was $226 and was estimated using the
Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at issuance of $5.75 per share;
seven-year contractual term; 95% volatility; 0% dividend rate; and a risk-free interest rate of 1.8%.

In connection with the additional $2,000 borrowed in August 2020, the Company issued warrants for 18,141 shares of its common stock at an
exercise price of $6.62 per share. The relative fair value of the 18,141 warrants was $94 and was estimated using the Black-Scholes-Merton option pricing
model  with  the  following  assumptions:  fair  value  of  the  Company’s  common  stock  at  issuance  of  $6.85  per  share;  seven-year  contractual  term;  95%
volatility; 0% dividend rate; and a risk-free interest rate of 0.4%.

These warrants (the “SWK Warrants”) are exercisable immediately and have a term of seven years from the date of issuance. The SWK Warrants
are subject to a cashless exercise feature, with the exercise price and number of shares issuable upon exercise subject to change in connection with stock
splits, dividends, reclassifications and other conditions.

The  Company  recorded  interest  expense  of  $884  and  $98  in  2020  and  2019,  respectively,  which  included  $121  and  $16,  respectively,  of  debt
discount amortization. The Company had accrued interest of $48 and $82 as of December 31, 2020 and 2019, respectively, which is included in accrued
liabilities in the accompanying balance sheets.

in November 2018. The gross proceeds were $20,055 from the Series A Preferred stock offering. The Series A Preferred shares, including accrued and
unpaid dividends, automatically converted to the Company’s common shares at the date of the IPO (See Note 7).

As of the date of the IPO on November 15, 2018, the liquidation value of the Series A Preferred was $21,746, which consisted of the issuance

amount of $20,055 plus accrued dividends of $1,691.

The  Series  A  Preferred  automatically  converted  to  common  shares  upon  completion  of  the  IPO  in  November  2018.  The  conversion  share
calculation was based on the $3.00 initial issue price for the Series A Preferred plus accrued and unpaid dividends, and automatically converted into shares
of  the  Company’s  common  stock  using  a  stated  divisor  conversion  price  equal  to  50%  of  the  IPO  price  to  the  public  which  was  $6.00  per  share.  In
accordance with relevant accounting literature, since the terms of the conversion option did not permit the Company to compute the additional number of
shares  that  it  would  need  to  issue  upon  conversion  of  the  Series  A  Preferred  when  the  contingent  event  occurred,  the  Company  recorded  the  beneficial
conversion amount of $21,747 as a deemed dividend at the date of the IPO in November 2018.

As a result of the Series A Preferred having a possible cash redemption feature in the event that an IPO or alternate financing was not completed
by December 31, 2018, the Series A Preferred was classified as temporary equity and not included as part of Company’s stockholders’ equity (deficit) prior
to the November 2018 IPO. In accordance with that classification, the $2,534 of issuance costs associated with the Series A Preferred offering were being
ratably accreted as a deemed dividend using the effective interest method through the expected redemption date.

Note 7 — Common Stock

The Company has 50,000,000 authorized shares of $0.001 par value common stock as per its Amended and Restated Certificate of Incorporation.
On January 1, 2018, the Company issued 54,745 restricted shares of its common stock to each of its four outside directors (218,980 total shares valued at
$300) as part of their compensation for board service to the Company in 2018. The restricted shares issued to the outside directors vested 25% at each
quarter-end in 2018 and were fully vested as of December 31, 2018. The Company accounted for the restricted stock awards (“RSAs”) in accordance with
ASC 718 (see Note 9).

In conjunction with the Company’s IPO in November 2018, the Series A Preferred shares, including accrued dividends, converted into 7,248,948

shares of the Company’s common stock, and the Company issued 4,140,000 additional shares of its common stock to investors in its IPO (see Note 1).

In March and April 2020, the Company entered into securities purchase agreements with various investors and sold an aggregate of 2,600,000 shares

of its common stock at a price of $3.00 per share and received $7,756 in net proceeds after deducting issuance costs associated with the sale.

In  March  2020,  the  Company  issued  379,474  shares  of  its  common  stock  to  Diurnal  Limited  (“Diurnal”)  as  a  milestone  fee  for  acquiring  the  U.S.
marketing rights to Alkindi Sprinkle®, an orphan drug product currently under review with the FDA (see Note 15). The shares were valued at $1,264 based
on the Company’s closing stock price on the date of issuance and this amount was recorded as a component of the Company’s research and development
expense and a corresponding increase to its additional paid-in-capital.

In  October  2020,  the  Company  issued  3,220,000  shares  of  its  common  stock  in  a  public  offering  at  an  offering  price  of  $7.00  per  share  and

received net proceeds of $21,026.

Note 7 — Common Stock (continued)

For the years ended December 31, 2020 and 2019, the Company issued 194,878 and 167,622 shares, respectively, of its common stock resulting from
stock option exercises under its 2018 Equity Incentive Plan (see Note 9). For the years ended December 31, 2020 and 2019, the Company issued 25,780
and 44,885 shares, respectively, under the Company’s Employee Stock Purchase Program (“ESPP”). In April 2020, the Company issued 15,190 shares of
its common stock as an RSA to a new employee. This RSA vests 25% every three months and will be 100% vested in April 2021.

During 2019, there were 97,088 warrant shares exercised (all on a cashless basis) resulting in 57,051 shares of common stock being issued by the

Company. There were no warrant exercises in the 2020 period.

Note 8 — Common Stock Warrants

In conjunction with the closing of the Series A Preferred offering in June 2017 (see Note 6), the Company issued a warrant to purchase 649,409
shares  of  its  common  stock  to  the  placement  agent  at  an  exercise  price  of  $3.00  per  share,  provided,  however,  upon  the  conversion  of  the  Series  A
Preferred,  the  warrant  adjusted  to  entitle  the  holder  to  purchase  shares  of  common  stock  equal  to  10.0%  of  the  shares  of  common  stock  issuable  upon
conversion of the Series A Preferred (excluding 191,000 shares of Series A Preferred that were purchased by insiders) and the exercise price would adjust
to the conversion price of the Series A Preferred. This warrant vested at issuance in June 2017. The Company used the BSM to value the warrant and the
fair value at the date of issuance was $479. Prior to the Company’s IPO in November 2018, the number of common shares issuable upon the exercise of
this  warrant  was  not  fixed  as  it  could  vary  by  a  factor  of  1.000  to  1.333  common  shares  per  warrant  share  in  accordance  with  the  IPO  price,  and  the
Company  considered  the  warrant  to  be  a  derivative  instrument.  The  $479  amount  was  recorded  as  a  component  of  the  issuance  costs  for  the  Series  A
Preferred in June 2017. As of December 31, 2017, the fair value of the warrant was $520.

As  of  November  15,  2018,  the  fair  value  of  the  warrants  was  $3,103  and  the  $2,583  increase  in  fair  value  during  2018  was  recorded  as  a
component of other income and expense. The fair value assumptions included an expected term of five years, expected volatility of 85%, a risk-free interest
rate of 2.9% and estimate of the conversion rate. These warrants were classified as warrant liability on the Company’s balance sheets prior to the IPO in
November 2018. In connection with the Company’s IPO, the number of shares issuable upon the exercise of these warrants became fixed at 704,184 shares
which eliminated the fair value adjustment after that date. At the IPO date, the warrant liability was reclassified to additional paid-in-capital.

During November 2018, in connection with the IPO, the Company issued warrants for 414,000 shares of its common stock to the placement agent

at an exercise price of $7.50 per share.

In connection with the SWK Credit Agreement, the Company issued warrants to SWK to purchase 51,239 shares of the Company’s common stock
(the “SWK Warrants”) with an exercise price of $5.86 per share. The SWK Warrants are exercisable immediately and have a term of seven years ending
November 13, 2026. The SWK Warrants are subject to a cashless exercise feature, with the exercise price and number of shares issuable upon exercise
subject to change in connection with stock splits, dividends, reclassifications and other conditions. The relative fair value of the SWK Warrants was $226
and was estimated using the Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at
issuance of $5.75 per share; seven-year contractual term; 95% volatility; 0% dividend rate; and a risk-free interest rate of 1.8%. The $226 relative fair value
for these warrants was reflected as a component of additional paid-in-capital in the Company’s balance sheet.

In connection with the additional $2,000 borrowed in August 2020 under the SWK Credit Agreement, the Company issued warrants for 18,141
shares of its common stock at an exercise price of $6.62 per share. The relative fair value of the 18,141 warrants was $94 and was estimated using the
Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at issuance of $6.85 per share;
seven-year  contractual  term;  95%  volatility;  0%  dividend  rate;  and  a  risk-free  interest  rate  of  0.4%.  The  $94  relative  fair  value  for  these  warrants  was
reflected as a component of additional paid-in-capital in the Company’s balance sheet.

The weighted average exercise price of the outstanding warrants for the consultant, placement agent and debt holder as of December 31, 2020 and

2019 was $3.17 and $3.13 per share, respectively.

Note 9 — Share-Based Payment Awards

The Company’s board of directors and stockholders approved the Eton Pharmaceuticals, Inc. 2017 Equity Incentive Plan in May 2017 (the “2017
Plan”), which authorized the issuance of up to 5,000,000 shares of the Company’s common stock. In conjunction with the Company’s IPO in November
2018, the Company’s stockholders and board of directors approved the 2018 Equity Incentive Plan (the “2018 Plan”) which succeeded the 2017 Plan. The
Company has granted RSAs, stock options and restricted stock units (“RSUs”) for its common stock under the 2017 Plan and 2018 Plan as detailed in the
tables below. There were 398,246 shares available for future issuance under the 2018 Plan as of December 31, 2020.

Shares that are expired, terminated, surrendered or canceled without having been fully exercised will be available for future awards under the 2018
Plan. In addition, the 2018 Plan provides that commencing January 1, 2019 and through January 1, 2028, the share reserve will be increased by 4% of the
total  number  of  shares  outstanding  as  of  the  preceding  December  31,  subject  to  a  reduction  at  the  discretion  of  the  Company’s  board  of  directors.  On
January 1, 2019, the share reserve was increased by 704,317 shares based on the 17,607,928 shares of common stock outstanding at December 31, 2018.
On  January  1,  2020,  the  share  reserve  was  increased  by  715,099  shares  based  on  the  17,877,486  shares  of  common  stock  outstanding  at  December  31,
2019. The exercise price for stock options granted is not less than the fair value of common stock as determined by the board of directors as of the date of
grant.  Prior  to  the  IPO,  the  Company’s  board  of  directors  valued  the  Company’s  common  stock,  taking  into  consideration  its  most  recently  available
valuation  of  common  stock  performed  by  third  parties  as  well  as  additional  factors  which  might  have  changed  since  the  date  of  the  most  recent
contemporaneous valuation through the date of grant. Following the IPO, the Company has used the closing stock price on the date of grant as the exercise
price.

On January 1, 2018, the Company issued 54,745 restricted shares of its common stock to each of its four outside directors (218,980 total shares). The
restricted shares issued to the outside directors vested 25% at each quarter-end in 2018 and became fully vested at December 31, 2018. In April 2020, the
Company issued 15,190 shares of its common stock as an RSA to a new employee. This RSA vests 25% every three months and will be 100% vested in
April 2021.

To date, all stock options issued have been non-qualified stock options and the exercise prices were set at the fair value for the shares at the dates
of  grant.  Options  generally  have  a  ten-year  life,  except  for  options  to  purchase  50,000  shares  of  the  Company’s  common  stock  granted  to  product
consultants  that  expire  within  five  years  if  the  Company  is  not  able  to  successfully  file  certain  product  submissions  to  the  FDA  prior  to  the  five-year
expiration date. Furthermore, these option awards to the Company’s product consultants do not vest unless certain product submissions are made to the
FDA, and accordingly, the Company has not recorded any expense for these contingently vesting option awards to its product consultants.

For the years ended December 31, 2020, 2019, and 2018, the Company’s total stock-based compensation expense was $2,576, $1,888 and $1,850,
respectively. Of these amounts, $2,295, $1,574 and $1,770 was recorded in general and administrative expenses, respectively, and $281, $314 and $80 was

Note 9 — Share-Based Payment Awards (continued)

Expected Term — The Company has opted to use the “simplified method” for estimating the expected term of options granted to employees and
directors, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally 10 years).
The expected term of options granted to non-employees equals the contractual life of the options.

Expected Volatility — Due to the Company’s limited operating history and a lack of Company-specific historical and implied volatility data, the
Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical
volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term
of the stock-based awards. The Company has continued this methodology plus given some limited weighting to its own volatility in the periods subsequent
to its November 2018 IPO.

Risk-Free Interest Rate — The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of

the Company’s stock options.

Expected Dividend — The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options

and therefore has estimated the dividend yield to be zero.

Fair value of Common Stock — Prior to the Company’s IPO in November 2018, the fair value of the shares of common stock underlying the
stock-based  awards  was  determined  by  the  board  of  directors,  with  input  from  management.  Because  there  was  no  public  market  for  the  Company’s
common stock, the board of directors determined the fair value of the common stock on the grant-date of the stock-based award by considering a number of
objective  and  subjective  factors,  including  enterprise  valuations  of  the  Company’s  common  stock  performed  by  an  unrelated  third-party  specialist,
valuations of comparable companies, sales of the Company’s convertible preferred stock to unrelated third parties, operating and financial performance, the
lack of liquidity of the Company’s capital stock, and general and industry-specific economic outlook. The board of directors intended all options granted to
be exercisable at a price per share not less than the estimated per share fair value of common stock underlying those options on the date of grant. Following
the IPO, the Company uses the closing stock price on the date of grant for the fair value of the common stock.

A summary of activity for RSAs and RSUs is as follows:

Note 9 — Share-Based Payment Awards (continued)

In December 2018, the Company’s board of directors adopted an initial offering of the Company’s common stock under the Company’s ESPP. The
Company’s ESPP provides for an initial reserve of 150,000 shares and this reserve is automatically increased on January 1 of each year by the lesser of 1%
of the outstanding common shares at December 31 of the preceding year or 150,000 shares, subject to reduction at the discretion of the Company’s board of
directors.

The initial offering began on December 17, 2018 and ended on December 10, 2019. The initial offering consisted of two purchase periods, with
the first purchase period ended on June 10, 2019 and the second purchase period ended on December 10, 2019. The terms of the ESPP permit employees of
the Company to use payroll deductions to purchase stock at a price per share that is at least the lesser of (1) 85% of the fair market value of a share of
common stock on the first date of an offering or (2) 85% of the fair market value of a share of common stock on the date of purchase. After the initial
offering period, subsequent twelve-month offering periods automatically commence over the term of the ESPP on the day that immediately follows the
conclusion  of  the  preceding  offering,  each  consisting  of  two  purchase  periods  approximately  six  months  in  duration  ending  on  or  around  June  10  and
December 10 each year, subject to a restart feature if the Company’s stock price drops at the end of a six-month period within the twelve-month offering
period.

The Company recorded an expense of $71, $112 and $5 in 2020, 2019 and 2018, respectively, related to the ESPP. The weighted average grant
date fair value of share awards in 2020, 2019 and 2018 was $2.32, $2.56 and $2.59 per share, respectively. Employees contributed $115 and $247 to the
ESPP during 2020 and 2019, respectively. Of these amounts, $18 and $16 at December 31, 2020 and 2019, respectively, is included in accrued liabilities in
the accompanying balance sheets.

Note 10 — Basic and Diluted Net Loss per Common Share

Basic and diluted net loss per share is computed using the weighted average number of shares of common stock outstanding during the period.
Common stock equivalents (using the treasury stock and “if converted” method) from stock options, unvested RSAs and RSUs, and warrants at December
31,  2020,  2019  and  2018  were  3,371,489,  3,590,465,  and  8,262,381,  respectively,  and  are  excluded  from  the  calculation  of  diluted  net  loss  per  share
because the effect is anti-dilutive. Included in the basic and diluted net loss per share calculation were RSUs awarded to directors that had vested, but the
issuance and delivery of the shares are deferred until the director retires from service as a director.

The following table shows the computation of basic and diluted net loss per common share:

Note 11 — Related Party Transactions

Harrow

Harrow was issued 3,500,000 shares of the Company’s common stock at the formation of the Company at the $0.001 par value per share price as
the  paid-in-capital  contribution  from  Harrow.  The  Company  and  Harrow  signed  licensing  agreements  for  two  products  developed  by  Harrow  whereby
Harrow assigned the product rights to the Company. The Company will pay Harrow a $50 milestone payment upon patent approval for each product and a
royalty fee at a rate of six percent on the net sales of those two products. On December 26, 2017, one of the products had its patent approved and a $50
milestone fee was recognized as R&D expense by the Company in 2017 and paid to Harrow in January 2018. In July 2018, the Company determined the
patent-approved product was not viable for its portfolio of product opportunities and Harrow paid the Company $50 to cancel the licensing agreement for
the one product and retain the product rights at Harrow.

On May 6, 2019, the Company entered into an Asset Purchase Agreement (the “CT-100 Asset Purchase Agreement”) with Harrow. Pursuant to the
CT-100 Asset Purchase Agreement, the Company sold all of its right, title and interest in CT-100 to Harrow, including any such product that incorporates or
utilizes  its  intellectual  property  rights  (a  “Product”  or,  collectively,  “Products”).  Pursuant  to  the  CT-100  Asset  Purchase  Agreement,  Harrow  will  make
certain  payments  to  the  Company  upon  the  achievement  of  certain  development  and  commercial  milestones.  In  addition,  Harrow  is  required  to  pay  the
Company a royalty in the low-single digit percentage range worldwide on a country-by-country basis on net sales for a period of the longer of 15 years
from the date of the first commercial sale of a product in a particular country or the time that a valid intellectual property claim on such Product remains in
force in the applicable country. The CT-100 Asset Purchase Agreement also contains customary representations, warranties, covenants and indemnities by
the parties.

As  part  of  the  early  start-up  for  the  Company’s  pharmaceutical  business,  key  executives  at  Harrow  received  1,500,000  shares  of  restricted
common stock in the Company for consulting services and certain Harrow managers also received options to purchase 130,000 shares of common stock
from the Company (20,000 of these options were forfeited in 2018). The restricted stock and stock options vested 100% after one year on April 30, 2018.
The Company recorded stock-based compensation expense of $0, $0 and $970 for the Harrow restricted common stock and $0, $0 and $51 for Harrow
stock options, respectively, for the years ended December 31, 2020, 2019 and 2018 as a component of its general and administrative expenses.

Additionally, the Chief Executive Officer of Harrow is a member of the Company’s board of directors.

Chief Executive Officer

The CEO has a partial interest in a company that the Company has partnered with for its EM-100 product as described below.

The  Company  acquired  the  exclusive  rights  to  sell  the  EM-100  product  in  the  United  States  pursuant  to  a  sales  and  marketing  agreement  (the
“Eyemax Agreement”) dated August 11, 2017 between the Company and Eyemax LLC (“Eyemax”), an entity affiliated with the Company’s CEO. The
Company also held a right of first refusal to obtain the exclusive license rights for geographic areas outside of the United States. Pursuant to the Eyemax
Agreement,  the  Company  was  responsible  for  all  costs  of  testing  and  FDA  approval  of  the  product,  other  than  the  FDA  filing  fee  which  was  paid  by
Eyemax. The Company was also to be responsible for commercializing the product in the United States at its expense. The Company paid Eyemax $250
upon execution of the Eyemax Agreement, which was recorded as a component of R&D expense. Under the terms of the original agreement, the Company
would pay Eyemax $250 upon FDA approval and $500 upon the first commercial sale of the product and pay Eyemax a royalty of 10% on the net sales of
all products. The Eyemax Agreement was for an initial term of 10 years from the date of the Eyemax Agreement, subject to successive two-year renewals
unless the Company elected to terminate the Eyemax Agreement. There were no amounts due under the terms of the Eyemax Agreement as of December
31, 2020 or 2019.

Note 11 — Related Party Transactions (continued)

On  February  18,  2019,  The  Company  entered  into  an  Amended  and  Restated  Agreement  with  Eyemax  amending  the  Sales  Agreement  (the
“Amended Agreement”). Pursuant to the Amended Agreement, Eyemax sold the Company all of its right, title and interest in EM-100, including any such
product  that  incorporates  or  utilizes  Eyemax’s  intellectual  property  rights.  Under  the  Amended  Agreement,  the  Company  assumed  certain  liabilities  of
Eyemax  under  its  Exclusive  Development  &  Supply  Agreement  with  Excelvision  SAS  dated  as  of  July  11,  2013,  as  amended  (the  “Excelvision
Agreement”),  with  respect  to  certain  territories  and  arising  during  certain  time  periods.  Pursuant  to  the  Amended  Agreement,  the  Company  remains
obligated to pay Eyemax two milestones payments: (i) one milestone payment for $250 upon regulatory approval in the territory by the FDA of the first
single agent product and (ii) one milestone payment for $500 following the first commercial sale of the first single agent product in the territory which was
paid in February 2021. Following payment of the milestones, the Company is entitled to retain all of the non-royalty transaction revenues and royalties up
to $2,000 (the “Recovery Amount”). After the Company has retained the full Recovery Amount, it is entitled to retain half of all royalty and non-royalty
transaction revenue. The Amended Agreement also contains customary representations, warranties, covenants and indemnities by the parties. The EM-100
asset and its associated product rights were sold to Bausch Health on February 18, 2019 and future potential royalties of twelve percent on Bausch Health
sales of EM-100, which was approved by the FDA in September 2020, will be split between Eyemax and the Company. The royalty from Bausch Health is
subject to reduction if a competitive product with the same active pharmaceutical ingredient is launched in the U.S. or if the EM-100 U.S market share falls
below a specified target percentage. There were no amounts due under the terms of the Amended Agreement as of December 31, 2020 or 2019.

Note 12 — Leases

The Company recognizes a right-of-use (“ROU”) asset and a lease liability on the balance sheet for substantially all leases, including operating

leases, and separates lease components from non-lease components related to its office space lease.

On January 12, 2018, the Company signed an amended lease agreement to lease additional office space adjacent to its current corporate office
space in Deer Park, Illinois. The amended lease was scheduled to expire at the end of March 2021. In October 2020, the Company renewed its office lease
for a two-year period through March 31, 2023 and recorded $195 in ROU assets and $195 in operating lease liabilities associate with the lease extension.
On March 7, 2018, the Company entered into a lease for laboratory space at a complex in Lake Zurich, Illinois. The lease commenced on March 7, 2018
and was scheduled to expire in February 2021. In November 2020, this laboratory lease was extended to June 2021 as the Company evaluates its future
laboratory operations requirements.

The Company does not have any lease contracts that contain: (1) an option to extend that the Company is reasonably certain to exercise, (2) an
option to terminate that the Company is reasonably certain to exercise, or (3) an option to extend (or not to terminate) in which exercise of the option is
controlled  by  the  lessor.  Additionally,  the  Company  does  not  have  any  leases  with  residual  value  guarantees  or  material  restrictive  covenants.  Lease
liabilities and their corresponding right-of-use assets have been recorded based on the present value of the future lease payments over the expected lease
term. One of the Company’s lease agreements contains provisions for escalating rent payments over the term of the lease.

The Company’s leases do not contain readily determinable implicit discount rates, and therefore, the Company was required to use its incremental
borrowing rate of 7.8% to discount the future lease payments based on information available at lease commencement. In October 2020, the new discount
rate  for  the  office  lease  extension  was  estimated  at  5.4%.  The  incremental  borrowing  rate  was  estimated  by  determining  the  rate  of  interest  that  the
Company  would  have  to  pay  to  borrow  on  a  collateralized  basis  over  a  similar  term  an  amount  equal  to  the  lease  payments  in  a  similar  economic
environment.

For the years ended December 31, 2020, 2019 and 2018, the Company recorded $139, $140, and $115, respectively, in rent expense.

The Company’s operating lease cost as presented in the “Research and Development” and “General and Administrative” captions in the statements
of operations was $55 and $84 and $55 and $85 for the years ended December 31, 2020 and 2019, respectively. Cash paid for amounts included in the
measurement of operating lease liabilities was $131 and $120 for years ended December 31, 2020 and 2019, respectively. The ROU asset amortization for
years ended December 31, 2020 and 2019 was $129 and $121, respectively, and is reflected in depreciation and amortization in the Company’s statements
of cash flows. As of December 31, 2020, the weighted-average remaining lease term was 2.2 years, and the weighted-average discount rate was 5.4%.

The table below presents the lease-related assets and liabilities recorded on the balance sheet as of December 31, 2020:

Note 13 – Income Taxes (continued)

The  Company  has  a  federal  and  state  NOL  carryforward  of  $57,008  as  of  December  31,  2020.  Under  the  Tax  Act,  federal  NOLs  incurred  in
taxable  years  ending  after  December  31,  2017  in  the  amount  of  $51,356  may  be  carried  forward  indefinitely,  but  the  deductibility  of  federal  NOLs
generated in tax years beginning before December 31, 2017 in the amount of $5,652 will expire in 2037. The state NOL carry forward will begin to expire
in 2029.

In  addition,  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended,  and  corresponding  provisions  of  state  law,  if  a
corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change (by value) in its equity ownership over a three-year

License and Product Development Agreements

The Company has entered into various agreements in addition to those discussed above which are described below.

The Company acquired the exclusive rights to sell the Cysteine injection product in the United States pursuant to a sales and marketing agreement
dated  November  17,  2017  with  an  unaffiliated  third  party  (the  “Sales  Agreement”).  Pursuant  to  the  Sales  Agreement,  the  licensor  is  responsible  for
obtaining FDA approval, at its expense, and the Company is responsible for commercializing the product in the United States at its expense. The Company
was  to  pay  the  third  party  50%  of  the  net  profit  from  the  sale  of  the  product,  however,  in  February  2020,  it  executed  an  amendment  to  the  Sales  and
Marketing  Agreement.  Under  the  revised  terms,  the  Company  will  be  responsible  for  paragraph  IV  related  litigation  and  will  be  entitled  to  62.5%  of
product profit. The initial term is for the first 10 years following the first commercial sale of the product.

The  Company  acquired  the  exclusive  license  to  develop,  manufacture  and  sell  oral  solution  Levothyroxine  in  the  United  States  pursuant  to  an
Exclusive License and Supply Agreement dated August 3, 2018 between the Company and Liqmeds Worldwide Limited (“LMW”), an unaffiliated entity.
Pursuant  to  the  agreement,  the  Company  was  to  be  responsible  for,  and  would  own,  all  regulatory  filings  and  approvals  at  its  expense,  provided  that  it
would have the right to recoup 35% of any regulatory filing fees from the initial profits from the sale of ET-103 and, provided further, the licensor would be
responsible for any bioequivalence study and would be responsible for 60% of the costs of such study. An affiliate of the licensor was to manufacture the
ET-103 and sell it to the Company at its cost. The Company paid the licensor $350 upon execution of the agreement and was to pay the licensor $1,500
upon the FDA’s acceptance of an NDA for review, $1,000 upon FDA approval, $1,500 upon issuance of patent covering ET-103 listed in the FDA’s Orange
Book and $500 in the event of product sales in excess of $10,000 in any calendar year. In addition, the Company was required to pay the licensor 35% of
the net profit from product sales. The license agreement was for an initial term of 10 years from the date of the first commercial sale of the product, subject
to two-year renewals unless either party elects to terminate no less than 12 months prior to the then current term. The agreement also contained customary
representations, warranties, covenants and indemnities by the parties. In November 2020, the Company terminated the development agreement with LMW
due to new adverse market competitive factors.

On February 8, 2019, the Company entered into an Exclusive Licensing and Supply Agreement (the “ET-202 License Agreement”) with Sintetica SA
(“Sintetica”) for marketing rights in the United States to Biorphen® which is used for the treatment of clinically important hypotension resulting primarily
from vasodilation in the setting of anesthesia. The product was submitted to the FDA for review and subsequently received FDA approval on October 21,
2019.  Pursuant  to  the  terms  of  the  ET-202  License  Agreement,  the  Company  is  responsible  for  marketing  activities  and  Sintetica  is  responsible  for
development, manufacturing, and the regulatory activities related to approval. The Company paid Sintetica a licensing payment of $2,000 upon execution
of the ET-202 License Agreement and $750 upon the commencement of commercial product shipments. Sintetica will supply Biorphen to the Company at
its  direct  costs  and  the  Company  will  retain  5%  of  net  sales  as  a  marketing  fee.  Sintetica  is  entitled  to  receive  the  first  $500  of  product  profits.  All
additional profit will be split 50% to the Company and 50% to Sintetica. The ET-202 License Agreement has a ten-year term from the first commercial sale
of Biorphen which occurred in November 2019. There was a gross loss for Biorphen for the year ended December 31, 2020 due to slower than anticipated
sales and a product price reduction through the Company’s wholesale customers.

On  February  8,  2019,  the  Company  also  entered  into  an  Exclusive  Licensing  and  Supply  Agreement  (the  “ET-203  License Agreement”)  with
Sintetica for marketing rights in the United States to ephedrine, an injectable product candidate for use in the hospital setting. Pursuant to the terms of the
ET-203 License Agreement, the Company will be responsible for marketing activities and Sintetica will be responsible for development, manufacturing,
and regulatory activities related to obtaining regulatory approval. The Company paid Sintetica a licensing payment of $1,000 upon execution of the ET-203
License Agreement  which  was  refunded  to  Eton  in  early  2020  due  to  the  FDA  not  accepting  the  ET-203  file  submission  by  Sintetica.  The  refund  was
reflected as a component of prepaid and other current assets on the Company’s balance sheet at December 31, 2019. The ET-203 product was successfully
resubmitted in late 2020 and the Company will pay a $600 milestone fee and will also pay $750 upon FDA approval and the commercial sale of the product
candidate. Upon approval, Sintetica will supply ET-203 to the Company at its direct costs. The Company will retain 5% of net sales as a marketing fee.
Sintetica will be entitled to receive the first $500 of product profits. All additional profit will be split 50% to the Company and 50% to Sintetica. The ET-
203 License Agreement has a ten-year term from first commercial sale of product.

Note 15 — Commitments and Contingencies (continued)

The three oral solution pediatric neurology product candidates discussed below, Topiramate, Zonisamide and Lamotrigine were developed by the
Company and its various product candidate development partners and the Company subsequently sold all its rights and interests in these three products to
Azurity Pharmaceuticals, Inc. (“Azurity”) in 2021 (see Note 16 — Subsequent Events).

During  the  years  ended  December  31,  2020,  2019  and  2018,  the  Company  worked  with  Tulex  Pharmaceuticals,  Inc.  (“Tulex”)  as  a  third-party
contract manufacturer to develop an oral solution for Topiramate (fka ET-101) which targets a neurological condition. The Company subsequently filed the
product with the FDA in October 2020 and paid a $1,438 filing fee.

On January 23, 2019, the Company entered into a Licensing and Supply Agreement (the “Agreement”) with LMW for Zonisamide oral liquid, a
development stage product candidate (“ET-104”). Pursuant to the terms of the Agreement, the Company was to be responsible for regulatory and marketing
activities. LMW will be responsible for development and manufacturing of ET-104. The Company paid the licensor $350 upon execution of the Agreement
and an additional $350 after receiving successful bioequivalence study results, and $325 upon the FDA’s acceptance of the NDA for review and will pay
$325 upon FDA approval of the NDA, $650 upon issuance of patent covering ET-104 listed in the FDA’s Orange Book and $500 in the event that product
sales in excess of $10,000 were achieved within a calendar year. In addition, the Company was required to pay the licensor 35% of the net profit from
product sales. The Agreement was for an initial term of 10 years from the date of the first commercial sale of the product. The Company was to retain sole
ownership of the NDA after expiration of the Agreement.

On  June  12,  2019,  the  Company  entered  into  an  Exclusive  Licensing  and  Supply  Agreement  (the  “ET-105  License  Agreement”)  with  Aucta
Pharmaceuticals, Inc. (“Aucta”) for marketing rights in the United States to Lamotrigine, an oral suspension product candidate for use as an adjunct therapy
for partial seizures, primary generalized tonic-clonic seizures, and generalized seizures of Lennox-Gastaut syndrome in patients two years of age and older.
Pursuant to the terms of the ET-105 License Agreement, the Company was to be responsible for marketing activities and Aucta will be responsible for
development, manufacturing, and regulatory activities related to obtaining regulatory approval. The Company paid Aucta a licensing payment of $2,000 in
August 2019 upon receiving an acceptance for review letter from the FDA and will pay $2,450 upon FDA approval and commercial sales of the product
candidate and another $1,000 upon issuance of an Orange-book listed patent. If Aucta successfully completes a Lamotrigine product line extension product,
Eton will pay $1,500 upon FDA acceptance of the product filing and $1,950 upon FDA approval and commercial sales of the extension product candidate.
Aucta will receive a low double-digit royalty on net sales and will be entitled to receive milestone payments of up to $18,000 based on commercial success
of the product, including:

● $1,000 when net sales exceed $10 million in a calendar year
● $2,000 when net sales exceed $20 million in a calendar year
● $5,000 when net sales exceed $50 million in a calendar year
● $10,000 when net sales exceed $100 million in a calendar year

Eton will remain responsible for certain licensing fee obligations owed to its development partners and Azurity will assume royalty or profit share

obligations owed to development partners

Note 15 — Commitments and Contingencies (continued)

On March 27, 2020, the Company entered into an Exclusive Licensing and Supply Agreement (the “Alkindi License Agreement”) with Diurnal for
marketing Alkindi Sprinkle in the United States. Alkindi Sprinkle’s New Drug Application (NDA) was approved by the FDA on September 29, 2020 as a
replacement therapy for pediatric adrenal insufficiency (AI), including congenital adrenal hyperplasia (CAH) in patients from birth to less than 17 years of
age.

For the initial licensing milestone fee, the Company paid Diurnal $3,500 in cash and issued 379,474 shares of its common stock to Diurnal which were
valued at $1,264 based on the Company’s closing stock price of $3.33 on March 26, 2020 (see Note 7). The total amount of $4,764 was recorded as a
component of research and development expense in the Company’s statement of operations for the year ended December 31, 2020. The Company will also
pay Diurnal $2,500 if the product obtains orphan drug exclusivity status from the FDA.

Indemnification

As permitted under Delaware law and in accordance with the Company’s Amended and Restated Bylaws, the Company is required to indemnify
its officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. The Company is also party to
indemnification agreements with its directors and officers. The Company believes the fair value of the indemnification rights and agreements is minimal.
Accordingly, the Company has not recorded any liabilities for these indemnification rights and agreements as of December 31, 2020 or 2019.

Note 16 — Subsequent Events

In  February  2021,  the  Company  sold  its  pediatric  neurology  portfolio  to  Azurity  Pharmaceuticals  (“Azurity”).  The  portfolio  included  the
Company’s Lamotrigine (ET-105), Zonisamide (ET-104), and Topiramate (ET-101) product candidates, which have all been submitted to the U.S. Food and
Drug Administration as new drug applications and are currently under review by the FDA.

Azurity will assume control of all three products and will be responsible for commercialization following regulatory approval. The Company will
support Azurity in the transition and through regulatory approval. Under the terms of the transaction, the Company will receive up to $45,000 in payments
from Azurity under the following schedule:

-

-

$15,000 at  closing,  of  which  $9,500  was  received  in  February  2021  and  $5,500  is  held  in  escrow  until  certain  product-related  milestones  are
achieved;
$15,000 upon achievement of FDA approval and product launch milestones; and
$15,000 upon achievement of commercial sales milestones.

In  addition,  the  Company  will  receive  a  single  digit  percentage  royalty  on  Azurity’s  net  sales  of  the  products.  The  Company  will  remain
responsible for certain licensing fee obligations owed to its development partners (see Note 15) and Azurity will assume royalty or profit share obligations
owed to the development partners. The Company paid milestones of $550 to Aucta Pharmaceuticals and $200 to Tulex Pharmaceuticals in February 2021
in  conjunction  with  the  sale  of  the  pediatric  neurology  products  to  Azurity.  The  Company’s  proceeds  from  the  transaction  will  be  used  for  business
development activities targeting additional late-stage orphan drug products.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

PART II (CONTINUED)

None.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are
designed  to  ensure  that  information  required  to  be  disclosed  by  us  in  reports  that  we  file  or  submit  under  the  Exchange  Act  is  recorded,  processed,
summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our
management, including our principal executive officer and our principal financial officer, to allow timely decisions regarding required disclosure.

The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there

can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

As of December 31, 2020, an evaluation was conducted under the supervision and with the participation of our management, including our Chief
Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based on this evaluation, such officers have
concluded that our disclosure controls and procedures are effective as of December 31, 2020.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for our Company, as such term
is defined in Rule 13a-15(f) under the Exchange Act. Our management conducted an evaluation, with the participation of our principal executive officer
and principal financial officer, of the effectiveness of our internal control over financial reporting as of December 31, 2020, based on the criteria set forth in
the  2013  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  this
evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2020.

This report does not include an attestation report of our independent registered public accounting firm regarding our internal control over financial

reporting, in accordance with applicable SEC rules that permit us to provide only management’s report in this report.

Changes in Internal Control over Financial Reporting

There  has  not  been  any  change  in  our  internal  control  over  financial  reporting  (as  defined  in  Rules  13a-15(f)  under  the  Exchange  Act)  that
occurred during the quarter ended December 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over
financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, do not expect that our disclosure controls or our internal
control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only
reasonable,  not  absolute,  assurance  that  the  control  system’s  objectives  will  be  met.  The  design  of  a  control  system  must  reflect  the  fact  that  there  are
resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  Further,  because  of  the  inherent  limitations  in  all  control
systems,  no  evaluation  of  controls  can  provide  absolute  assurance  that  misstatements  due  to  error  or  fraud  will  not  occur  or  that  all  control  issues  and
instances  of  fraud,  if  any,  have  been  detected.  These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty  and  that
breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or
more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood
of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of
any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions
or deterioration in the degree of compliance with policies or procedures.

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF
THE SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.6

Introduction

Eton  Pharmaceuticals,  Inc.  (the  “Company,”  “we,”  “us”  or  “our”)  has  one  security  registered  pursuant  to  Section  12  of  the  Securities  Exchange  Act  of
1934, as amended, which is our common stock. Our common stock is listed on The Nasdaq Global Market under the symbol “ETON”.

The following summary does not purport to be complete and is qualified by reference to certain provisions of the Delaware General Corporation Law, as
amended (the “DGCL”), our Amended and Restated Certificate of Incorporation, dated November 15, 2018 (our “Certificate of Incorporation”), and our
Amended and Restated Bylaws, effective November 15, 2018 (our “Bylaws”), each of which has been filed as an exhibit to the Annual Report on Form 10-
K filed with the Securities and Exchange Commission to which this exhibit is attached and is hereby incorporated by reference.

Authorized Capital Stock

Our  authorized  capital  stock  consists  of  50,000,000  shares  of  common  stock,  par  value  $0.001  per  share,  and  10,000,000  shares  of  preferred  stock,  par
value $0.001 per share.

Preferred Stock

Our Certificate of Incorporation authorizes our board of directors to issue preferred stock from time to time in one or more series and to fix the number of
shares  and  to  determine  or  alter  for  each  such  series,  such  voting  powers,  full  or  limited,  or  no  voting  powers,  and  such  designation,  preferences,  and
relative, participating, optional, or other rights and such qualifications, limitations, or restrictions thereof, as shall be stated and expressed in the resolution
or resolutions adopted by the board of directors providing for the issuance of such shares and as may be permitted by the DGCL. Our board of directors is
also expressly authorized to increase or decrease the number of shares of any series subsequent to the issuance of shares of that series, but not below the
number of shares of such series then outstanding. In case the number of shares of any series shall be decreased in accordance with the foregoing sentence,
the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of
such  series.  The  number  of  authorized  shares  of  preferred  stock  may  be  increased  or  decreased  (but  not  below  the  number  of  shares  thereof  then
outstanding)  by  the  affirmative  vote  of  the  holders  of  a  majority  of  the  voting  power  of  the  stock  of  the  Company  entitled  to  vote  thereon,  without  a
separate  vote  of  the  holders  of  the  preferred  stock,  or  of  any  series  thereof,  unless  a  vote  of  any  such  holders  is  required  pursuant  to  the  terms  of  any
certificate of designation filed with respect to any series of preferred stock.

Common Stock

Dividend Rights

Subject to preferences to which holders of preferred stock may be entitled, holders of common stock are entitled to receive ratably such dividends, if any, as
may be declared from time to time by our board of directors out of funds legally available therefor. We do not anticipate paying cash dividends on our
common  stock  in  the  foreseeable  future.  We  intend  to  retain  all  available  funds  and  any  future  earnings  to  fund  the  development  and  expansion  of  our
business.

Voting Rights

Each holder of common stock is entitled to one vote for each share on each matter properly submitted to the stockholders of the Company; provided, that a
holder of common stock is not entitled to vote on any amendment to the Certificate of Incorporation (including any certificate of designation filed with
respect to any series of preferred stock) that relates solely to the terms of a series of outstanding preferred stock if the holders of such affected series of
preferred  stock  are  entitled  to  vote  thereon.  In  all  matters  other  than  the  election  of  directors,  stockholder  approval  requires  the  affirmative  vote  of  the
majority of the holders of our common stock entitled to vote on the subject matter unless the matter is one upon which, by express provision of law, our
Certificate of Incorporation or our Bylaws, a different vote is required. Directors are elected by a plurality of the votes of the shares present in person or
represented by proxy and entitled to vote on the election of directors.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Classification of Board of Directors

The board of directors are divided into three classes designated as Class I, Class II and Class III, respectively. Each director is expected to be elected to
hold office for a three-year term or until the election and qualification of his or her successor in office.

No Preemptive or Similar Rights

Holders of our common stock do not have preemptive rights, and our common stock is not convertible or redeemable.

Right to Receive Liquidation Distributions

In the event of our liquidation, dissolution or winding up, holders of common stock would be entitled to share in our assets remaining after the payment of
liabilities  and  the  satisfaction  of  any  liquidation  preference  granted  the  holders  of  any  outstanding  shares  of  any  senior  class  of  securities.  The  rights,
preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series
of preferred stock which we may designate in the future.

Section 203 of the Delaware Corporation Law

We  are  subject  to  Section  203  of  the  DGCL,  which  prevents  an  “interested  stockholder”  (defined  in  Section  203  of  the  DGCL,  generally,  as  a  person
owning 15% or more of a corporation’s outstanding voting stock), from engaging in a “business combination” (as defined in Section 203 of the DGCL)
with a publicly held Delaware corporation for three years following the date such person became an interested stockholder, unless:

●

●

●

before  such  person  became  an  interested  stockholder,  the  board  of  directors  of  the  corporation  approved  the  transaction  in  which  the
interested stockholder became an interested stockholder or approved the business combination;

upon  consummation  of  the  transaction  that  resulted  in  the  interested  stockholders  becoming  an  interested  stockholder,  the  interested
stockholder owns at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding stock held
by directors who are also officers of the corporation and by employee stock plans that do not provide employees with the rights to determine
confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer); or

following the  transaction  in  which  such  person  became  an  interested  stockholder,  the  business  combination  is  approved  by  the  board  of
directors of the corporation and authorized at a meeting of stockholders by the affirmative vote of the holders of two-thirds of the outstanding
voting stock of the corporation not owned by the interested stockholder.

The provisions of Section 203 of the DGCL could make a takeover of the Company difficult.

Effect of Certain Provisions of Our Certificate of Incorporation and Bylaws

Our Certificate of Incorporation and Bylaws include provisions that may have the effect of discouraging, delaying or preventing a change in control or an
unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the
market price for the shares held by our stockholders. Certain of these provisions are summarized in the following paragraphs.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Effects of Authorized but Unissued Common Stock.

One  of  the  effects  of  the  existence  of  authorized  but  unissued  common  stock  may  be  to  enable  our  board  of  directors  to  make  more  difficult  or  to
discourage  an  attempt  to  obtain  control  of  our  Company  by  means  of  a  merger,  tender  offer,  proxy  contest  or  otherwise,  and  thereby  to  protect  the
continuity of management. If, in the due exercise of its fiduciary obligations, the board of directors were to determine that a takeover proposal was not in
our  best  interest,  such  shares  could  be  issued  by  the  board  of  directors  without  stockholder  approval  in  one  or  more  transactions  that  might  prevent  or
render  more  difficult  or  costly  the  completion  of  the  takeover  transaction  by  diluting  the  voting  or  other  rights  of  the  proposed  acquirer  or  insurgent
stockholder group, by putting a substantial voting block in institutional or other hands that might undertake to support the position of the incumbent board
of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise.

Cumulative Voting.

Our Amended and Restated Certificate of Incorporation does not provide for cumulative voting in the election of directors, which would allow holders of
less than a majority of the stock to elect some directors.

Vacancies.

Our Amended and Restated Certificate of Incorporation provides that all vacancies may be filled by the affirmative vote of a majority of directors then in
office, even if less than a quorum.

Special Meeting of Stockholders and Stockholder Action by Written Consent.

A special meeting of stockholders may only be called by our president, board of directors, or such officers or other persons as our board may designate at
any time and for any purpose or purposes as shall be stated in the notice of the meeting.

 
 
 
 
 
 
 
 
 
 
 
 
ETON PHARMACEUTICALS, INC.

2018 EQUITY INCENTIVE PLAN

LAST AMENDED JANUARY 2021

Exhibit 10.11

1.

GENERAL.

(a) Successor to and Continuation of Prior Plan. The Plan is intended as the successor to and continuation of the Eton Pharmaceuticals, Inc.
2017 Equity Incentive Plan (the “Prior Plan”). From and after 12:01 a.m. Eastern Time on the IPO Date, no additional stock awards will be granted under
the Prior Plan. All Awards granted on or after 12:01 a.m. Eastern Time on the IPO Date will be granted under this Plan. All stock awards granted under the
Prior Plan will remain subject to the terms of the Prior Plan.

(i) Any shares that would otherwise remain available for future grants under the Prior Plan as of 12:01 a.m. Eastern Time on the IPO Date
(the “Prior Plan’s Available Reserve”) will cease to be available under the Prior Plan at such time. Instead, that number of shares of Common Stock equal
to the Prior Plan’s Available Reserve will be added to the Share Reserve (as further described in Section 3(a) below) and will be immediately available for
grants and issuance pursuant to Stock Awards hereunder, up to the maximum number set forth in Section 3(a) below.

(ii) In addition, from and after 12:01 a.m. Eastern Time on the IPO Date, any shares subject, at such time, to outstanding stock awards
granted under the Prior Plan that (i) expire or terminate for any reason prior to exercise or settlement; (ii) are forfeited because of the failure to meet a
contingency or condition required to vest such shares or otherwise return to the Company; or (iii) are reacquired, withheld (or not issued) to satisfy a tax
withholding obligation in connection with an award or to satisfy the purchase price or exercise price of a stock award (such shares the “Returning Shares”)
will immediately be added to the Share Reserve (as further described in Section 3(a) below) as and when such shares become Returning Shares, up to the
maximum number set forth in Section 3(a) below.

(b) Eligible Award Recipients. Employees, Directors and Consultants are eligible to receive Awards.

(c) Available  Awards.  The  Plan  provides  for  the  grant  of  the  following  types  of  Awards:  (i)  Incentive  Stock  Options,  (ii)  Nonstatutory  Stock
Options, (iii) Stock Appreciation Rights (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock Awards, (vii) Performance
Cash Awards, and (viii) Other Stock Awards.

(d)  Purpose.  The  Plan,  through  the  granting  of  Awards,  is  intended  to  help  the  Company  secure  and  retain  the  services  of  eligible  award
recipients, provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and provide a means by which
the eligible recipients may benefit from increases in value of the Common Stock.

2.

ADMINISTRATION.

(a)  Administration  by  Board.  The  Board  will  administer  the  Plan.  The  Board  may  delegate  administration  of  the  Plan  to  a  Committee  or

Committees, as provided in Section 2(c).

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(b) Powers of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To  determine  (A)  who  will  be  granted  Awards;  (B)  when  and  how  each  Award  will  be  granted;  (C)  what  type  of  Award  will  be
granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or
Common Stock under the Award; (E) the number of shares of Common Stock subject to, or the cash value of, an Award; and (F) the Fair Market Value
applicable to a Stock Award.

(ii)  To  construe  and  interpret  the  Plan  and  Awards  granted  under  it,  and  to  establish,  amend  and  revoke  rules  and  regulations  for
administration of the Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any
Award Agreement or in the written terms of a Performance Cash Award, in a manner and to the extent it will deem necessary or expedient to make the Plan
or Award fully effective.

(iii) To settle all controversies regarding the Plan and Awards granted under it.

(iv) To  accelerate,  in  whole  or  in  part,  the  time  at  which  an  Award  may  be  exercised  or  vest  (or  the  time  at  which  cash  or  shares  of

Common Stock may be issued in settlement thereof).

(v)  To  suspend  or  terminate  the  Plan  at  any  time.  Except  as  otherwise  provided  in  the  Plan  or  an  Award  Agreement,  suspension  or
termination  of  the  Plan  will  not  materially  impair  a  Participant’s  rights  under  the  Participant’s  then-outstanding Award  without  the  Participant’s  written
consent except as provided in subsection (viii) below.

(vi) To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting amendments
relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or bringing the Plan or Awards
granted under the Plan into compliance with the requirements for Incentive Stock Options or ensuring that they are exempt from or compliant with the
requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. If required by
applicable law or listing requirements, and except as provided in Section 9(a) relating to Capitalization Adjustments, the Company will seek stockholder
approval of any amendment of the Plan that (A) materially increases the number of shares of Common Stock available for issuance under the Plan, (B)
materially expands the class of individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants under the
Plan, (D) materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (E) materially extends the term of the
Plan,  or  (F)  materially  expands  the  types  of  Awards  available  for  issuance  under  the  Plan.  Except  as  otherwise  provided  in  the  Plan  or  an  Award
Agreement, no amendment of the Plan will materially impair a Participant’s rights under an outstanding Award without the Participant’s written consent.

satisfy the requirements of (A) Section 422 of the Code regarding incentive stock options or (B) Rule 16b-3.

(vii) To submit any amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to

 
 
 
 
 
 
 
 
 
 
 
(viii) To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more Awards, including, but
not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified
limits in the Plan that are not subject to Board discretion; provided however, that a Participant’s rights under any Award will not be impaired by any such
amendment  unless  (A)  the  Company  requests  the  consent  of  the  affected  Participant,  and  (B)  such  Participant  consents  in  writing.  Notwithstanding  the
foregoing, (1) a Participant’s rights will not be deemed to have been impaired by any such amendment if the Board, in its sole discretion, determines that
the amendment, taken as a whole, does not materially impair the Participant’s rights, and (2) subject to the limitations of applicable law, if any, the Board
may amend the terms of any one or more Awards without the affected Participant’s consent (A) to maintain the qualified status of the Award as an Incentive
Stock Option under Section 422 of the Code; (B) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award
solely  because  it  impairs  the  qualified  status  of  the  Award  as  an  Incentive  Stock  Option  under  Section  422  of  the  Code;  (C)  to  clarify  the  manner  of
exemption  from,  or  to  bring  the  Award  into  compliance  with,  Section  409A  of  the  Code;  or  (D)  to  comply  with  other  applicable  laws  or  listing
requirements.

(ix) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests

of the Company and that are not in conflict with the provisions of the Plan or Awards.

(x) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors or
Consultants  who  are  foreign  nationals  or  employed  outside  the  United  States  (provided  that  Board  approval  will  not  be  necessary  for  immaterial
modifications to the Plan or any Award Agreement that are required for compliance with the laws of the relevant foreign jurisdiction).

(xi) To effect, with the consent of any adversely affected Participant, (A) the reduction of the exercise, purchase or strike price of any
outstanding  Stock  Award;  (B)  the  cancellation  of  any  outstanding  Stock  Award  and  the  grant  in  substitution  therefor  of  a  new  (1)  Option  or  SAR,  (2)
Restricted Stock Award, (3) Restricted Stock Unit Award, (4) Other Stock Award, (5) cash and/or (6) other valuable consideration determined by the Board,
in  its  sole  discretion,  with  any  such  substituted  award  (x)  covering  the  same  or  a  different  number  of  shares  of  Common  Stock  as  the  cancelled  Stock
Award and (y) granted under the Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under
generally accepted accounting principles.

(c)

Delegation to Committee.

(i) General. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration of the
Plan  is  delegated  to  a  Committee,  the  Committee  will  have,  in  connection  with  the  administration  of  the  Plan,  the  powers  theretofore  possessed  by  the
Board that have been delegated to the Committee, including the power to delegate to a subcommittee of the Committee any of the administrative powers
the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee, as applicable). Any
delegation  of  administrative  powers  will  be  reflected  in  resolutions,  not  inconsistent  with  the  provisions  of  the  Plan,  adopted  from  time  to  time  by  the
Board or Committee (as applicable). The Committee may, at any time, abolish the subcommittee and/or revest in the Committee any powers delegated to
the subcommittee. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board
some or all of the powers previously delegated.

(ii) Rule 16b-3 Compliance. The Committee may consist solely of two or more Non-Employee Directors, in accordance with Rule 16b-

3.

 
 
 
 
 
 
 
 
 
 
 
(d)  Delegation  to  an  Officer.  The  Board  may  delegate  to  one  or  more  Officers  the  authority  to  do  one  or  both  of  the  following  (i)  designate
Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by applicable law, other Stock Awards) and, to the
extent  permitted  by  applicable  law,  the  terms  of  such  Awards,  and  (ii)  determine  the  number  of  shares  of  Common  Stock  to  be  subject  to  such  Stock
Awards  granted  to  such  Employees;  provided, however,  that  the  Board  resolutions  regarding  such  delegation  will  specify  the  total  number  of  shares  of
Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself or herself.
Any such Stock Awards will be granted on the form of Stock Award Agreement most recently approved for use by the Committee or the Board, unless
otherwise provided in the resolutions approving the delegation authority. The Board may not delegate authority to an Officer who is acting solely in the
capacity of an Officer (and not also as a Director) to determine the Fair Market Value pursuant to Section 13(w)(iii) below.

(e) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board in good faith will not be subject to review

by any person and will be final, binding and conclusive on all persons.

3.

SHARES SUBJECT TO THE PLAN.

(a) Share Reserve. Subject to Section 9(a) relating to Capitalization Adjustments, and the following sentence regarding the annual increase, the
aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards will not exceed 5,000,000 shares (the “Share Reserve”), which
is (i) the number of shares subject to the Prior Plan’s Available Reserve plus (ii) the number of shares that are Returning Shares, as such shares become
available from time to time. In addition, the Share Reserve will automatically increase on January 1st of each year, for a period of not more than ten years,
commencing on January 1st of the year following the year in which the IPO Date occurs and ending on (and including) January 1, 2028, in an amount equal
to  4%  of  the  total  number  of  shares  of  Capital  Stock  outstanding  on  December  31st  of  the  preceding  calendar  year.  Notwithstanding  the  foregoing,  the
Board  may  act  prior  to  January  1st  of  a  given  year  to  provide  that  there  will  be  no  January  1st  increase  in  the  Share  Reserve  for  such  year  or  that  the
increase in the Share Reserve for such year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding
sentence.

For clarity, the Share Reserve in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued pursuant to the
Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a). Shares may be issued in connection
with  a  merger  or  acquisition  as  permitted  by  Nasdaq  Listing  Rule  5635(c)  or,  if  applicable,  NYSE  Listed  Company  Manual  Section  303A.08,  AMEX
Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance under the Plan.

(b) Reversion of Shares to the Share Reserve.  If  a  Stock  Award  or  any  portion  thereof  (i)  expires  or  otherwise  terminates  without  all  of  the
shares  covered  by  such  Stock  Award  having  been  issued  or  (ii)  is  settled  in  cash  (i.e.,  the  Participant  receives  cash  rather  than  stock),  such  expiration,
termination or settlement will not reduce (or otherwise offset) the number of shares of Common Stock that may be available for issuance under the Plan. If
any  shares  of  Common  Stock  issued  pursuant  to  a  Stock  Award  are  forfeited  back  to  or  repurchased  or  reacquired  by  the  Company  for  any  reason,
including  because  of  the  failure  to  meet  a  contingency  or  condition  required  to  vest  such  shares  in  the  Participant,  then  the  shares  that  are  forfeited  or
repurchased or reacquired will revert to and again become available for issuance under the Plan. Any shares reacquired by the Company in satisfaction of
tax  withholding  obligations  on  a  Stock  Award  or  as  consideration  for  the  exercise  or  purchase  price  of  a  Stock  Award  will  again  become  available  for
issuance under the Plan.

(c) Incentive Stock Option Limit. Subject to the Share Reserve and Section 9(a) relating to Capitalization Adjustments, the aggregate maximum

number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options will be 1,000,000 shares of Common Stock.

 
 
 
 
 
 
 
 
 
 
(d) Limitation on Grants to Non-Employee Directors.  The  maximum  number  of  shares  of  Common  Stock  subject  to  Stock  Awards  granted
under the Plan or otherwise during a single calendar year to any Non-Employee Director, taken together with any cash fees paid by the Company to such
Non- Employee Director during such calendar year for service on the Board, will not exceed $500,000 in total value (calculating the value of any such
Stock Awards based on the grant date fair value of such Stock Awards for financial reporting purposes), or, with respect to the calendar year in which a
Non-Employee Director is first appointed or elected to the Board, $800,000.

(e) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares

repurchased by the Company on the open market or otherwise.

4.

ELIGIBILITY.

(a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a “parent corporation”
or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and 424(f) of the Code). Stock Awards other than Incentive Stock Options
may  be  granted  to  Employees,  Directors  and  Consultants;  provided,  however,  that  Stock  Awards  may  not  be  granted  to  Employees,  Directors  and
Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in Rule 405 of the Securities Act, unless
(i) the stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards
are granted pursuant to a corporate transaction such as a spin off transaction), (ii) the Company, in consultation with its legal counsel, has determined that
such Stock Awards are otherwise exempt from Section 409A of the Code, or (iii) the Company, in consultation with its legal counsel, has determined that
such Stock Awards comply with the distribution requirements of Section 409A of the Code.

(b) Ten Percent Stockholders. A Ten Percent Stockholder will not be granted an Incentive Stock Option unless the exercise price of such Option

is at least 110% of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five years from the date of grant.

5.

PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS.

Each  Option  or  SAR  will  be  in  such  form  and  will  contain  such  terms  and  conditions  as  the  Board  deems  appropriate.  All  Options  will  be
separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or
certificates  will  be  issued  for  shares  of  Common  Stock  purchased  on  exercise  of  each  type  of  Option.  If  an  Option  is  not  specifically  designated  as  an
Incentive Stock Option, or if an Option is designated as an Incentive Stock Option but some portion or all of the Option fails to qualify as an Incentive
Stock Option under the applicable rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or
SARs need not be identical; provided, however, that each Award Agreement will conform to (through incorporation of provisions hereof by reference in the
applicable Award Agreement or otherwise) the substance of each of the following provisions:

(a) Term. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR will be exercisable after the expiration

of ten (10) years from the date of its grant or such shorter period specified in the Award Agreement.

 
 
 
 
 
 
 
 
 
 
 
(b) Exercise Price. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, the exercise or strike price of each Option or
SAR  will  be  not  less  than  100%  of  the  Fair  Market  Value  of  the  Common  Stock  subject  to  the  Option  or  SAR  on  the  date  the  Award  is  granted.
Notwithstanding  the  foregoing,  an  Option  or  SAR  may  be  granted  with  an  exercise  or  strike  price  lower  than  100%  of  the  Fair  Market  Value  of  the
Common Stock subject to the Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right
pursuant to a corporate transaction and in a manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a) of the
Code. Each SAR will be denominated in shares of Common Stock equivalents.

(c) Purchase Price for Options. The purchase price of Common Stock acquired pursuant to the exercise of an Option may be paid, to the extent
permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The
Board will have the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain
methods) and to grant Options that require the consent of the Company to use a particular method of payment. The permitted methods of payment are as
follows:

(i) by cash, check, bank draft or money order payable to the Company;

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of the
stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate
exercise price to the Company from the sales proceeds;

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock;

(iv) if an Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will reduce the number
of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate
exercise price; provided, however, that the Company will accept a cash or other payment from the Participant to the extent of any remaining balance of the
aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. Shares of Common Stock will no longer be subject to
an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise price pursuant to the “net
exercise,” (B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or

(v) in any other form of legal consideration that may be acceptable to the Board and specified in the applicable Award Agreement.

(d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written notice of exercise to the Company in
compliance with the provisions of the Stock Appreciation Right Agreement evidencing such SAR. The appreciation distribution payable on the exercise of
a SAR will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the SAR) of a number
of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and with respect to
which the Participant is exercising the SAR on such date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to
which the Participant is exercising the SAR on such date. The appreciation distribution may be paid in Common Stock, in cash, in any combination of the
two or in any other form of consideration, as determined by the Board and contained in the Award Agreement evidencing such SAR.

 
 
 
 
 
 
 
 
 
 
 
 
(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability of Options and
SARs as the Board will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of
Options and SARs will apply:

(i) Restrictions on Transfer. An Option or SAR may be transferred either (i) by instrument to the Participant’s “Immediate Family” (as
defined below), (ii) by instrument to an inter vivos or testamentary trust (or other entity) in which the Option or SAR or Stock Award is to be passed to the
Participant’s designated beneficiaries, or (iii) by gift to charitable institutions. Any transferee of the Participant’s rights shall succeed and be subject to all of
the terms of the applicable Award and the Plan. “Immediate Family” means any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former
spouse,  sibling,  niece,  nephew,  mother-in-law,  father-in-law,  son-in-law,  daughter-in-law,  brother-in-law,  or  sister-in-law,  and  shall  include  adoptive
relationships. Otherwise, an Option or SAR will not be transferable except by will or by the laws of descent and distribution (or pursuant to subsections (ii)
and  (iii)  below)  and  will  be  exercisable  during  the  lifetime  of  the  Participant  only  by  the  Participant.  In  addition,  the  Board  may  permit  transfer  of  the
Option or SAR in a manner that is not prohibited by applicable tax and securities laws. Except as explicitly provided herein, neither an Option nor a SAR
may be transferred for consideration.

(ii) Domestic Relations Orders. Subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred
pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury
Regulation Section 1.421-1(b)(2). If an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of
such transfer.

(iii) Beneficiary Designation. Subject to the approval of the Board or a duly authorized Officer, a Participant may, by delivering written
notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, on the death of the Participant, will
thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of
such a designation, upon the death of the Participant, the executor or administrator of the Participant’s estate will be entitled to exercise the Option or SAR
and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at
any time, including due to any conclusion by the Company that such designation would be inconsistent with the provisions of applicable laws.

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and become exercisable in periodic
installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may
not  be  exercised  (which  may  be  based  on  the  satisfaction  of  Performance  Goals  or  other  criteria)  as  the  Board  may  deem  appropriate.  The  vesting
provisions  of  individual  Options  or  SARs  may  vary.  The  provisions  of  this  Section  5(f)  are  subject  to  any  Option  or  SAR  provisions  governing  the
minimum number of shares of Common Stock as to which an Option or SAR may be exercised.

(g)  Termination  of  Continuous  Service.  Except  as  otherwise  provided  in  the  applicable  Award  Agreement  or  other  agreement  between  the
Participant  and  the  Company,  if  a  Participant’s  Continuous  Service  terminates  (other  than  for  Cause  and  other  than  upon  the  Participant’s  death  or
Disability), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of
termination of Continuous Service) within the period of time ending on the earlier of (i) the date that is three (3) months following the termination of the
Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award Agreement, which period will not be less than thirty
(30) days if necessary to comply with applicable laws unless such termination is for Cause) and (ii) the expiration of the term of the Option or SAR as set
forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR (as applicable) within
the applicable time frame, the Option or SAR will terminate.

 
 
 
 
 
 
 
 
 
(h) Extension of Termination Date. Except as otherwise provided in the applicable Award Agreement or other written agreement between the
Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause
and other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would
violate the registration requirements under the Securities Act, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of
time (that need not be consecutive) equal to the applicable post termination exercise period after the termination of the Participant’s Continuous Service
during which the exercise of the Option or SAR would not be in violation of such registration requirements, and (ii) the expiration of the term of the Option
or  SAR  as  set  forth  in  the  applicable  Award  Agreement.  In  addition,  unless  otherwise  provided  in  a  Participant’s Award  Agreement,  if  the  sale  of  any
Common Stock received on exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would
violate the Company’s insider trading policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a period of months (that need not
be consecutive) equal to the applicable post- termination exercise period after the termination of the Participant’s Continuous Service during which the sale
of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration
of the term of the Option or SAR as set forth in the applicable Award Agreement.

(i) Disability of Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the
Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR
(to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such
period of time ending on the earlier of (i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period
specified in the Award Agreement, which period will not be less than six (6) months if necessary to comply with applicable laws) and (ii) the expiration of
the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her
Option or SAR within the applicable time frame, the Option or SAR (as applicable) will terminate.

(j) Death of Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the
Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if any)
specified in the Award Agreement for exercisability after the termination of the Participant’s Continuous Service for a reason other than death, then the
Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s
estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR
upon the Participant’s death, but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer
or shorter period specified in the Award Agreement, which period will not be less than six (6) months if necessary to comply with applicable laws) and (ii)
the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised
within the applicable time frame, the Option or SAR (as applicable) will terminate.

(k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award Agreement or other individual written agreement
between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will terminate
immediately upon such Participant’s termination of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR
from and after the time of such termination of Continuous Service.

 
 
 
 
 
 
 
(l) Non-Exempt Employees.  If  an  Option  or  SAR  is  granted  to  an  Employee  who  is  a  non-  exempt  employee  for  purposes  of  the  Fair  Labor
Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six (6) months following
the  date  of  grant  of  the  Option  or  SAR  (although  the  Award  may  vest  prior  to  such  date).  Consistent  with  the  provisions  of  the  Worker  Economic
Opportunity  Act,  (i)  if  such  non-exempt  Employee  dies  or  suffers  a  Disability,  (ii)  upon  a  Corporate  Transaction  in  which  such  Option  or  SAR  is  not
assumed,  continued,  or  substituted,  (iii)  upon  a  Change  in  Control,  or  (iv)  upon  the  Participant’s  retirement  (as  such  term  may  be  defined  in  the
Participant’s  Award  Agreement,  in  another  agreement  between  the  Participant  and  the  Company,  or,  if  no  such  definition,  in  accordance  with  the
Company’s then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised earlier than six (6) months
following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the
exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. To the extent permitted and/or required for compliance with the
Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of
any shares under any other Stock Award will be exempt from the employee’s regular rate of pay, the provisions of this Section 5(l) will apply to all Stock
Awards and are hereby incorporated by reference into such Stock Award Agreements.

  6.

PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS AND SARS.

(a) Restricted Stock Awards. Each Restricted Stock Award Agreement will be in such form and will contain such terms and conditions as the
Board deems appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares of Common Stock may be (i) held in book
entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (ii) evidenced by a certificate, which
certificate will be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change
from  time  to  time,  and  the  terms  and  conditions  of  separate  Restricted  Stock  Award  Agreements  need  not  be  identical.  Each  Restricted  Stock  Award
Agreement  will  conform  to  (through  incorporation  of  the  provisions  hereof  by  reference  in  the  agreement  or  otherwise)  the  substance  of  each  of  the
following provisions:

(i) Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash, check, bank draft or money order payable to
the Company, (B) past or future services to the Company or an Affiliate, or (C) any other form of legal consideration that may be acceptable to the Board,
in its sole discretion, and permissible under applicable law.

Company in accordance with a vesting schedule to be determined by the Board.

(ii)  Vesting.  Shares  of  Common  Stock  awarded  under  the  Restricted  Stock  Award  Agreement  may  be  subject  to  forfeiture  to  the

(iii)  Termination  of  Participant’s  Continuous  Service.  If  a  Participant’s  Continuous  Service  terminates,  the  Company  may  receive
through  a  forfeiture  condition  or  a  repurchase  right  any  or  all  of  the  shares  of  Common  Stock  held  by  the  Participant  as  of  the  date  of  termination  of
Continuous Service under the terms of the Restricted Stock Award Agreement.

(iv)  Transferability.  Rights  to  acquire  shares  of  Common  Stock  under  Restricted  Stock  Awards  may  be  transferred  either  (i)  by
instrument to the Participant’s “Immediate Family” (as defined below), (ii) by instrument to an inter vivos or testamentary trust (or other entity) in which
the Option or SAR or Stock Award is to be passed to the Participant’s designated beneficiaries, or (iii) by gift to charitable institutions. Any transferee of
the  Participant’s  rights  shall  succeed  and  be  subject  to  all  of  the  terms  of  the  applicable  Award  and  the  Plan.  “Immediate  Family”  means  any  child,
stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-
law, brother-in-law, or sister-in-law, and shall include adoptive relationships. Otherwise, rights to acquire shares of Common Stock under the Restricted
Stock  Award  Agreement  will  be  transferable  by  the  Participant  only  upon  such  terms  and  conditions  as  are  set  forth  in  the  Restricted  Stock  Award
Agreement, as the Board will determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award Agreement remains
subject to the terms of the Restricted Stock Award Agreement.

(v) Dividends. A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will be subject to the same

vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate.

 
 
 
 
 
 
 
 
 
 
 
(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms and conditions
as the Board deems appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and
conditions  of  separate  Restricted  Stock  Unit  Award  Agreements  need  not  be  identical.  Each  Restricted  Stock  Unit  Award  Agreement  will  conform  to
(through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions:

(i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine the consideration, if any, to be paid by
the  Participant  upon  delivery  of  each  share  of  Common  Stock  subject  to  the  Restricted  Stock  Unit  Award.  The  consideration  to  be  paid  (if  any)  by  the
Participant  for  each  share  of  Common  Stock  subject  to  a  Restricted  Stock  Unit  Award  may  be  paid  in  any  form  of  legal  consideration  that  may  be
acceptable to the Board, in its sole discretion, and permissible under applicable law.

vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate.

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions on or conditions to the

(iii) Payment.  A  Restricted  Stock  Unit  Award  may  be  settled  by  the  delivery  of  shares  of  Common  Stock,  their  cash  equivalent,  any

combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement.

(iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may impose
such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to
a time after the vesting of such Restricted Stock Unit Award.

(v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted Stock
Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend
equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the
Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same
terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate.

(vi)  Termination  of  Participant’s  Continuous  Service.  Except  as  otherwise  provided  in  the  applicable  Restricted  Stock  Unit Award
Agreement or other written agreement between a Participant and the Company or an Affiliate, such portion of the Restricted Stock Unit Award that has not
vested will be forfeited upon the Participant’s termination of Continuous Service.

(c)

Performance Awards.

(i) Performance Stock Awards. A Performance Stock Award is a Stock Award that is payable (including that may be granted, may vest
or may be exercised) contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but
need not, require the Participant’s completion of a specified period of Continuous Service. The length of any Performance Period, the Performance Goals to
be  achieved  during  the  Performance  Period,  and  the  measure  of  whether  and  to  what  degree  such  Performance  Goals  have  been  attained  will  be
conclusively determined by the Board or Committee, in its sole discretion. In addition, to the extent permitted by applicable law and the applicable Award
Agreement, the Board or the Committee may determine that cash may be used in payment of Performance Stock Awards.

 
 
 
 
 
 
 
 
 
 
 
 
 
(ii) Performance Cash Awards.  A  Performance  Cash  Award  is  a  cash  award  that  is  payable  contingent  upon  the  attainment  during  a
Performance  Period  of  certain  Performance  Goals.  A  Performance  Cash  Award  may  also  require  the  completion  of  a  specified  period  of  Continuous
Service.  At  the  time  of  grant  of  a  Performance  Cash  Award,  the  length  of  any  Performance  Period,  the  Performance  Goals  to  be  achieved  during  the
Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be conclusively determined by the
Board or Committee, in its sole discretion. The Board or Committee may specify the form of payment of Performance Cash Awards, which may be cash or
other  property,  or  may  provide  for  a  Participant  to  have  the  option  for  his  or  her  Performance  Cash  Award,  or  such  portion  thereof  as  the  Board  may
specify, to be paid in whole or in part in cash or other property.

(iii) Board Discretion. The Board retains the discretion to adjust or eliminate the compensation or economic benefit due upon attainment
of Performance Goals and to define the manner of calculating the Performance Criteria it selects to use for a Performance Period. Partial achievement of
the specified criteria may result in the payment or vesting corresponding to the degree of achievement as specified in the Stock Award Agreement or the
written terms of a Performance Cash Award.

(d)  Other  Stock  Awards.  Other  forms  of  Stock  Awards  valued  in  whole  or  in  part  by  reference  to,  or  otherwise  based  on,  Common  Stock,
including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the
Common Stock at the time of grant) may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions
of this Section 6. Subject to the provisions of the Plan, the Board will have sole and complete authority to determine the persons to whom and the time or
times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to
such Other Stock Awards and all other terms and conditions of such Other Stock Awards.

7.

COVENANTS OF THE COMPANY.

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to satisfy

then-outstanding Stock Awards.

(b) Securities Law Compliance. The Company will seek to obtain from each regulatory commission or agency having jurisdiction over the Plan,
as necessary, such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise or vesting of the Stock
Awards; provided, however, that this undertaking will not require the Company to register under the Securities Act or other securities or applicable laws,
the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable cost,
the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary or advisable
for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common
Stock upon exercise or vesting of such Stock Awards unless and until such authority is obtained. A Participant will not be eligible for the grant of an Award
or the subsequent issuance of cash or Common Stock pursuant to the Award if such grant or issuance would be in violation of any applicable securities law.

 
 
 
 
 
 
 
 
 
(c) No Obligation to Notify or Minimize Taxes. The Company will have no duty or obligation to any Participant to advise such holder as to the
tax treatment or time or manner of exercising such Stock Award. Furthermore, the Company will have no duty or obligation to warn or otherwise advise
such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or
obligation to minimize the tax consequences of an Award to the holder of such Award.

8.

MISCELLANEOUS.

(a) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Stock Awards will constitute

general funds of the Company.

(b) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will
be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or
letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board
consents, resolutions or minutes) documenting the corporate action approving the grant contain terms (e.g., exercise price, vesting schedule or number of
shares)  that  are  inconsistent  with  those  in  the  Award Agreement  or  related  grant  documents  as  a  result  of  a  clerical  error  in  the  papering  of  the  Award
Agreement or related grant documents, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the
Award Agreement or related grant documents.

(c) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of
Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common
Stock under, the Award pursuant to its terms, and (ii) the issuance of the Common Stock subject to such Award has been entered into the books and records
of the Company.

(d) No Employment or Other Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in
connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the
capacity in effect at the time the Award was granted or will affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee
with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or
an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of
the state or foreign jurisdiction in which the Company or the Affiliate is domiciled or incorporated, as the case may be.

(e) Change in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of his or her services for the
Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a
change in status from a full-time Employee to a part-time Employee or takes an extended leave of absence) after the date of grant of any Award to the
Participant,  the  Board  has  the  right  in  its  sole  discretion  to  (x)  make  a  corresponding  reduction  in  the  number  of  shares  or  cash  amount  subject  to  any
portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination
with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no
right with respect to any portion of the Award that is so reduced or extended.

 
 
 
 
 
 
 
 
 
 
(f) Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock
with  respect  to  which  Incentive  Stock  Options  are  exercisable  for  the  first  time  by  any  Optionholder  during  any  calendar  year  (under  all  plans  of  the
Company  and  any  Affiliates)  exceeds  $100,000  (or  such  other  limit  established  in  the  Code)  or  otherwise  does  not  comply  with  the  rules  governing
Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not
comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s).

(g) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Award,
(i)  to  give  written  assurances  satisfactory  to  the  Company  as  to  the  Participant’s  knowledge  and  experience  in  financial  and  business  matters  and/or  to
employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and
that such Participant is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award; and (ii) to
give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own
account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given
pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock
Award  has  been  registered  under  a  then  currently  effective  registration  statement  under  the  Securities  Act,  or  (B)  as  to  any  particular  requirement,  a
determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws.
The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

(h)  Withholding  Obligations.  Unless  prohibited  by  the  terms  of  an  Award  Agreement,  the  Company  may,  in  its  sole  discretion,  satisfy  any
federal, state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the
Participant  to  tender  a  cash  payment;  (ii)  withholding  shares  of  Common  Stock  from  the  shares  of  Common  Stock  issued  or  otherwise  issuable  to  the
Participant in connection with the Stock Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the maximum
amount  of  tax  required  to  be  withheld  by  law  (or  such  lesser  amount  as  may  be  necessary  to  avoid  classification  of  the  Stock  Award  as  a  liability  for
financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the
Participant; or (v) by such other method as may be set forth in the Award Agreement.

(i)  Electronic  Delivery.  Any  reference  herein  to  a  “written”  agreement  or  document  will  include  any  agreement  or  document  delivered
electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium
controlled by the Company to which the Participant has access).

(j) Deferrals. To the extent permitted by applicable law, the Board, in its sole discretion, may determine that the delivery of Common Stock or the
payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for
deferral elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section
409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise providing services to the Company. The
Board is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive payments, including lump
sum  payments,  following  the  Participant’s  termination  of  Continuous  Service,  and  implement  such  other  terms  and  conditions  consistent  with  the
provisions of the Plan and in accordance with applicable law.

 
 
 
 
 
 
 
 
(k) Clawback/Recovery.  All  Awards  granted  under  the  Plan  will  be  subject  to  recoupment  in  accordance  with  any  clawback  policy  that  the
Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are
listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, the Board may
impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate, including but
not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of an event
constituting Cause. No recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntary terminate employment
upon a “resignation for good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company.

(l)  Compliance  with  Section  409A  of  the  Code.  Unless  otherwise  expressly  provided  for  in  an  Award  Agreement,  the  Plan  and  Award
Agreements  will  be  interpreted  to  the  greatest  extent  possible  in  a  manner  that  makes  the  Plan  and  the  Awards  granted  hereunder  exempt  from  Section
409A  of  the  Code,  and,  to  the  extent  not  so  exempt,  in  compliance  with  Section  409A  of  the  Code.  If  the  Board  determines  that  any  Award  granted
hereunder  is  not  exempt  from  and  is  therefore  subject  to  Section  409A  of  the  Code,  the  Award Agreement  evidencing  such  Award  will  incorporate  the
terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on
terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in
this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant holding
an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the Code, no
distribution  or  payment  of  any  amount  that  is  due  because  of  a  “separation  from  service”  (as  defined  in  Section  409A  of  the  Code  without  regard  to
alternative definitions thereunder) will be issued or paid before the date that is six months following the date of such Participant’s “separation from service”
or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code,
and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original
schedule.

9.

ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.

(a)  Capitalization  Adjustments.  In  the  event  of  a  Capitalization  Adjustment,  the  Board  will  appropriately  and  proportionately  adjust:  (i)  the
class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the
share  reserve  is  to  increase  automatically  each  year  pursuant  to  Section  3(a),  (iii)  the  class(es)  and  maximum  number  of  securities  that  may  be  issued
pursuant to the exercise of Incentive Stock Options pursuant to Section 3(c), (iv) the class(es) and maximum number of securities that may be awarded to
any Non- Employee Director pursuant to Section 3(d), and (v) the class(es) and number of securities and price per share of stock subject to outstanding
Stock Awards. The Board will make such adjustments, and its determination will be final, binding and conclusive.

(b) Dissolution. Except as otherwise provided in the Stock Award Agreement, in the event of a Dissolution of the Company, all outstanding Stock
Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s
right of repurchase) will terminate immediately prior to the completion of such Dissolution, and the shares of Common Stock subject to the Company’s
repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such
Stock Award is providing Continuous Service; provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become
fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated)
before the Dissolution is completed but contingent on its completion.

 
 
 
 
 
 
 
 
(c) Transaction. The following provisions will apply to Stock Awards in the event of a Transaction unless otherwise provided in the instrument
evidencing  the  Stock  Award  or  any  other  written  agreement  between  the  Company  or  any  Affiliate  and  the  Participant  or  unless  otherwise  expressly
provided by the Board at the time of grant of a Stock Award. In the event of a Transaction, then, notwithstanding any other provision of the Plan, the Board
may take one or more of the following actions with respect to Stock Awards, contingent upon the closing or completion of the Transaction:

(i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume
or  continue  the  Stock  Award  or  to  substitute  a  similar  stock  award  for  the  Stock  Award  (including,  but  not  limited  to,  an  award  to  acquire  the  same
consideration paid to the stockholders of the Company pursuant to the Transaction);

pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company);

(ii)  arrange  for  the  assignment  of  any  reacquisition  or  repurchase  rights  held  by  the  Company  in  respect  of  Common  Stock  issued

(iii)  accelerate  the  vesting,  in  whole  or  in  part,  of  the  Stock  Award  (and,  if  applicable,  the  time  at  which  the  Stock  Award  may  be
exercised) to a date prior to the effective time of such Transaction as the Board determines (or, if the Board does not determine such a date, to the date that
is five days prior to the effective date of the Transaction), with such Stock Award terminating if not exercised (if applicable) at or prior to the effective time
of the Transaction; provided, however,  that  the  Board  may  require  Participants  to  complete  and  deliver  to  the  Company  a  notice  of  exercise  before  the
effective date of a Transaction, which exercise is contingent upon the effectiveness of such Transaction;

Award;

(iv) arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Stock

(v) cancel or arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of the

Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and

(vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value of the property the
Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Transaction, over (B) any exercise
price payable by such holder in connection with such exercise. For clarity, this payment may be $0 if the value of the property is equal to or less than the
exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of the Company’s Common

(g) “Cause” will have the meaning ascribed to such term in any written agreement between the Participant and the Company defining such term
and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of the following events: (i) such Participant’s

unauthorized use or disclosure of the Company’s confidential information or trade secrets; or (v) such Participant’s gross misconduct. The determination
that a termination of the Participant’s Continuous Service is either for Cause or without Cause will be made by the Company, in its sole discretion. Any
determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards
held by such Participant will have no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose.

(h) “Change in Control” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following

events:

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than 50% of the
combined  voting  power  of  the  Company’s  then  outstanding  securities  other  than  by  virtue  of  a  merger,  consolidation  or  similar  transaction.
Notwithstanding the foregoing, a Change in Control will not be deemed to occur (A) on account of the acquisition of securities of the Company directly
from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person
that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company
through the issuance of equity securities, (C) on account of the acquisition of securities of the Company by any individual who is, on the IPO Date, either
an executive officer or a Director (either, an “IPO Investor”) and/or any entity in which an IPO Investor has a direct or indirect interest (whether in the
form  of  voting  rights  or  participation  in  profits  or  capital  contributions)  of  more  than  50%  (collectively,  the  “IPO Entities”)  or  on  account  of  the  IPO
Entities continuing to hold shares that come to represent more than 50% of the combined voting power of the Company’s then outstanding securities as a
result of the conversion of any class of the Company’s securities into another class of the Company’s securities having a different number of votes per share
pursuant to the conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation; or (D) solely because the level of
Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a
result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in
Control  would  occur  (but  for  the  operation  of  this  sentence)  as  a  result  of  the  acquisition  of  voting  securities  by  the  Company,  and  after  such  share
acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred,
increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in
Control will be deemed to occur;

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately
after  the  consummation  of  such  merger,  consolidation  or  similar  transaction,  the  stockholders  of  the  Company  immediately  prior  thereto  do  not  Own,
directly or indirectly, either (A) outstanding voting securities representing more than 50% of the combined outstanding voting power of the surviving Entity
in such merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of the surviving Entity in
such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities
of the Company immediately prior to such transaction; provided, however, that a merger, consolidation or similar transaction will not constitute a Change in
Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the surviving
Entity or its parent are owned by the IPO Entities;

 
 
 
 
 
 
 
(iii) there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the
Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and
its Subsidiaries to an Entity, more than 50% of the combined voting power of the voting securities of which are Owned by stockholders of the Company in
substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease, license or
other disposition; provided, however,  that  a  sale,  lease,  exclusive  license  or  other  disposition  of  all  or  substantially  all  of  the  consolidated  assets  of  the
Company and its Subsidiaries will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing
more than 50% of the combined voting power of the acquiring Entity or its parent are owned by the IPO Entities;

(iv) the stockholders of the Company approve or the Board approves a plan of complete dissolution or liquidation of the Company, or a

complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation; or

(v) individuals who, on the IPO Date, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a
majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new Board member was
approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member will, for purposes of this Plan,
be considered as a member of the Incumbent Board.

Notwithstanding  the  foregoing  definition  or  any  other  provision  of  the  Plan,  (A)  the  term  Change  in  Control  will  not  include  a  sale  of  assets,
merger or other transaction effected exclusively for the purpose of changing the domicile of the Company and (B) the definition of Change in Control (or
any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant will supersede the foregoing definition
with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such
an individual written agreement, the foregoing definition will apply.

(i) “Code” means the Internal Revenue Code of 1986, as amended, including any applicable regulations and guidance thereunder.

services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services.
However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the
Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act
is available to register either the offer or the sale of the Company’s securities to such person.

(n) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant,

Consultant or Director or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the
Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that if the Entity for which
a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, in its sole discretion, such Participant’s Continuous Service
will  be  considered  to  have  terminated  on  the  date  such  Entity  ceases  to  qualify  as  an  Affiliate.  To  the  extent  permitted  by  law,  the  Board  or  the  chief
executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i)
any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers
between  the  Company,  an  Affiliate,  or  their  successors.  Notwithstanding  the  foregoing,  a  leave  of  absence  will  be  treated  as  Continuous  Service  for
purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of
absence agreement or policy applicable to the Participant, or as otherwise required by law.

(o) “Corporate Transaction”  means  the  consummation,  in  a  single  transaction  or  in  a  series  of  related  transactions,  of  any  one  or  more  of  the

such medical evidence as the Board deems warranted under the circumstances.

(r) “Dissolution”  means  when  the  Company,  after  having  executed  a  certificate  of  dissolution  with  the  State  of  Delaware  (or  other  applicable
state), has completely wound up its affairs. Conversion of the Company into a Limited Liability Company (or any other pass-through entity) will not be
considered a “Dissolution” for purposes of the Plan.

 
 
 
 
 
 
 
 
 
 
 
 
 
(s) “Employee” means any person employed by the Company or an Affiliate. However, service solely as a Director, or payment of a fee for such

(u) “Exchange Act” means the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder.

securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities.

(i) If the Common Stock is listed on any established stock exchange or traded on any established market, the Fair Market Value of a share
of Common Stock will be, unless otherwise determined by the Board, the closing sales price for such stock as quoted on such exchange or market (or the
exchange  or  market  with  the  greatest  volume  of  trading  in  the  Common  Stock)  on  the  date  of  determination,  as  reported  in  a  source  the  Board  deems
reliable.

the Fair Market Value will be the closing selling price on the last preceding date for which such quotation exists.

(ii) Unless otherwise provided by the Board, if there is no closing sales price for the Common Stock on the date of determination, then
